Sucuri review: cloud-based WordPress security with post-hack cleanup

Sucuri is a cloud-based WordPress security platform that protects your website with a Web Application Firewall (WAF) at the DNS level. The company specializes in post-hack cleanup and helps restore your site after an attack. With over 1 million protected websites, Sucuri is an established name in WordPress security. In this review, we test all features, performance, and pricing.

Sucuri was founded in 2010 by security experts and was acquired by GoDaddy in 2017. The service combines proactive protection via the cloud firewall with reactive cleanup services when your site gets hacked anyway. This makes Sucuri unique – most security plugins only detect problems but don't fix them.

The main difference from plugins like Wordfence is that Sucuri works at the DNS level. All your traffic goes through Sucuri's servers before reaching your website. Malicious traffic is blocked there. This completely offloads your server but requires you to adjust DNS settings and trust Sucuri with all your traffic.

What exactly is Sucuri?

Sucuri is a security-as-a-service platform with three main components: a cloud-based WAF, a malware monitoring service, and post-hack cleanup assistance. The firewall blocks attacks before they reach your server. Monitoring scans your site daily for malware. If you get hacked, Sucuri's team helps clean your site.

The cloud firewall runs on Sucuri's global network of servers. You change your DNS settings so your domain points to Sucuri's servers instead of directly to your hosting. Visitors notice nothing – the firewall is transparent. But attackers never reach your real server IP.

The platform also contains a CDN (Content Delivery Network) that caches your static content on edge servers worldwide. This speeds up your site for international visitors and reduces server load. The CDN is optional but a welcome bonus for most sites.

Cloud-based vs endpoint security

The fundamental difference between Sucuri and endpoint plugins is where security runs. Sucuri runs on external servers before your hosting. Endpoint plugins like Wordfence run on your own WordPress server.

Cloud security has major advantages. Your server is completely offloaded – firewall filtering happens elsewhere. DDoS attacks never reach your hosting because all traffic goes through Sucuri's network. Your real server IP remains hidden, complicating targeted attacks.

The disadvantage is you must trust a third party with all your traffic. Sucuri sees all requests and responses between your site and visitors. For sites with privacy-sensitive data, this is a consideration. You also add an extra hop that can increase latency, though the CDN usually compensates for this.

Endpoint plugins see deeper into requests because they run within WordPress. They have access to POST data, cookies, and session information. Cloud firewalls only see headers and URL parameters unless you share SSL certificates. For complex attacks exploiting POST data, endpoint protection can be more effective.

Installation and DNS configuration

Signing up for Sucuri starts at sucuri.net where you create an account and choose a plan. After payment, you get access to the Sucuri dashboard where you add your website. You also install the free Sucuri Security plugin in WordPress for monitoring and logging.

Real protection comes from the cloud firewall, and that requires DNS changes. Sucuri gives you two nameservers to set in your domain registrar. This routes all your traffic via Sucuri's network. This change can take 24-48 hours to propagate globally through DNS propagation.

DNS setup step by step

Log into your domain registrar where you bought your domain name. Go to DNS management and find nameserver settings. Replace your current nameservers with the two Sucuri provides. These look like ns1.sucuricloud.com and ns2.sucuricloud.com.

Before making the change, document your old nameservers. If problems arise, you can switch back. The DNS change is reversible but during the switch, your site can be temporarily unreachable if something goes wrong.

Sucuri's dashboard verifies if your DNS is correctly configured. It checks if your domain points to their servers. Once everything is correct, the firewall activates and protection begins. You see traffic statistics and blocked attacks in real-time.

For subdomains or complex DNS setups with multiple records, you can also use CNAME records instead of nameserver changes. This gives more control but is technically more complex. Sucuri documentation contains guides for different scenarios.

WordPress plugin installation

Install the free Sucuri Security plugin via Plugins > Add New in WordPress. This plugin is free for everyone and offers security hardening features, audit logging, and monitoring. The plugin communicates with your paid Sucuri account to synchronize malware scans.

After activation, go to Sucuri Security > Settings and enter your API key from your Sucuri dashboard. This links the plugin to your account. Now you see scan results and security alerts directly in WordPress instead of only on sucuri.net.

The plugin adds security hardening options: hardening file permissions, removing WordPress version numbers, blocking PHP execution in uploads directory, and more. These features work independently of your paid Sucuri service.

Cloud firewall features

The Sucuri Cloud WAF blocks attacks based on a continuously updated ruleset. It protects against SQL injection, XSS, remote code execution, and other OWASP Top 10 vulnerabilities. The firewall also learns from traffic patterns to detect suspicious behavior.

Virtual patching

A powerful feature is virtual patching. When a plugin or theme has a security vulnerability but no patch is available yet, Sucuri can deploy a firewall rule that blocks that specific vulnerability. Your site is protected without updating the vulnerable plugin.

This is crucial for zero-day exploits where no fix exists. Endpoint plugins can't protect against unknown vulnerabilities unless they detect the vulnerable plugin and disable it. Sucuri blocks the exploit attempt regardless of which plugin is vulnerable.

Virtual patches are automatically rolled out to all customers as soon as Sucuri identifies a new vulnerability. The security team monitors WordPress security mailing lists, CVE databases, and their own network to quickly find new threats.

DDoS protection and rate limiting

DDoS (Distributed Denial of Service) attacks flood your server with traffic to take it offline. Sucuri's network absorbs this traffic before it reaches your hosting. It filters legitimate traffic from bot requests and only sends real visitors through.

Rate limiting prevents individual IPs or bots from overloading your site. You can set limits for requests per second, per minute, or per hour. Aggressive bots exceeding these limits are automatically temporarily blocked.

Geographic blocking lets you block traffic from specific countries. If you only have Dutch customers, you can block traffic from other countries. This reduces attacks because many hacking attempts come from certain regions where you don't do business anyway.

CDN and caching

Sucuri's firewall includes a built-in CDN that caches static content (images, CSS, JavaScript) on edge servers worldwide. Visitors get content delivered from the nearest edge location, reducing load times especially for international visitors.

The CDN is optionally configurable. You can determine which content types are cached and for how long. WordPress dynamic content is not cached by default to prevent users from seeing old versions after updates.

For WooCommerce sites, you must configure caching to exclude checkout pages and account pages. Otherwise, customers might see old cart contents or experience login issues. Sucuri has preset configurations for popular plugins like WooCommerce and Easy Digital Downloads.

Malware monitoring and scanning

Sucuri scans your website daily for malware, blacklist status, and website integrity. The scanner checks external blacklists like Google Safe Browsing, Norton, and McAfee to see if your site is marked as malicious. If you're on a blacklist, Sucuri alerts you immediately.

Server-side scanning

The malware scanner uses two methods: remote scanning and optional server-side scanning. Remote scanning visits your site as a regular user and analyzes HTML output for suspicious scripts, iframes, or redirects. This detects client-side malware like injected spam links.

Server-side scanning requires you to install the Sucuri plugin or give FTP/SSH access. The scanner then logs into your server and checks files directly. This detects backdoors, webshells, and malware in PHP files not visible in the frontend.

Server-side scanning is more thorough but requires more permissions. For sites not wanting to give server access, remote scanning offers reasonable protection. It detects infections as soon as they become active and generate output.

Blacklist monitoring

Sucuri checks multiple blacklist databases daily. Google Safe Browsing warns users when they visit a "dangerous site." Norton, McAfee, Yandex, and other security vendors maintain their own blacklists. If your site gets hacked and serves spam or malware, you can end up on these lists.

Blacklist status is disastrous for your business. Visitors see large red warnings and leave your site. Google can remove you from search results. Traffic plummets. Sucuri monitors these lists and alerts you immediately if your site gets blacklisted.

More importantly: Sucuri helps with blacklist removal. After cleaning the infection, you submit a removal request. This process can take weeks and requires proof your site is clean. Sucuri's cleanup services give you this proof and speed up removal.

Post-hack cleanup services

The killer feature distinguishing Sucuri from plugins is post-hack cleanup assistance. If your site gets hacked and you have Sucuri, their security team cleans your site. For many customers, this is the primary reason to choose Sucuri over endpoint plugins.

How does cleanup work?

When your site is hacked and malware is detected, you open a support ticket with Sucuri. The incident response team analyzes the infection to determine how hackers gained access and what they changed. They identify all infected files, database entries, and backdoors.

The team cleans infected files by replacing them with clean versions from the WordPress repository or your backups. Database malware like spam comments, rogue admin accounts, or injected scripts are removed. All backdoors are found and closed.

Crucially, Sucuri also analyzes how the hack happened. Was it a weak password, outdated plugin, or server vulnerability? This root cause analysis prevents re-infection. There's little point in cleanup if hackers can get back in the next day.

Unlimited cleanup for Platform customers

The standard Basic plan includes cleanup but with limitations. Platform and higher get unlimited malware removal during your subscription. If you get hacked again, Sucuri cleans your site again without extra costs.

This is huge peace of mind for high-risk sites. Webshops and high-traffic sites are attractive targets. Even with preventive measures, a zero-day exploit can hit you. Unlimited cleanup means you don't need to be a security expert yourself or hire expensive consultants.

Response time is according to Sucuri 6 hours average for emergency cleanup. This means your site can be clean within a business day. For business-critical sites, this fast response is worth gold. DIY troubleshooting can take days if you don't know what to look for.

Free vs paid plans

Sucuri has a free WordPress plugin with basic security features, but the real value is in the paid cloud firewall and cleanup services. There are three paid tiers: Basic, Pro, and Business with increasing features and priority.

The Basic plan costs €199 per year for one website. This includes the cloud WAF, DDoS protection, CDN, daily malware scans, and basic malware removal. The firewall is updated once per day with new rules. Response time for cleanup is "best effort" without SLA.

Platform plan (recommended)

The Platform plan is €299 per year and the sweet spot for most professional sites. You get unlimited malware removal – if you get hacked again, Sucuri keeps helping without extra costs. Firewall update frequency goes to 12 hours, so you're protected faster against new threats.

Platform also adds priority support with faster response times. Sucuri aims for 2-4 hour first response on support tickets. For emergency cleanup during business hours, this is typically resolved within 6 hours. This significantly minimizes downtime.

You also get SSL certificate support. Sucuri can install your existing SSL cert on their edge servers so HTTPS traffic works correctly. For Let's Encrypt users, Sucuri can integrate automatic renewal.

Professional and Business tiers

The Professional plan (€499/year) and Business plan (custom pricing, approximately €999/year) are for enterprise sites with very high uptime requirements. Firewall updates are real-time. You get a dedicated account manager. Response times are contractually defined in an SLA.

These tiers add advanced features like multi-user access controls, custom WAF rules, API access, and detailed traffic analytics. For e-commerce sites with high volumes or SaaS platforms, these investments are justified.

For most WordPress sites, these high-end plans are overkill. A webshop doing €50k/month benefits from Professional for guaranteed uptime. A personal blog or small business site has enough with Platform.

Pros and cons

Pros:

Post-hack cleanup included: Sucuri's big differentiator is they clean your site after a hack. Plugins only detect malware but don't fix it. For non-technical site owners, this service is invaluable. You don't need to hire a security expert for €1000+ per incident.

Complete server offloading: Because the firewall runs on Sucuri's servers, it doesn't burden your hosting. Endpoint plugins like Wordfence use CPU and RAM with every request. Sucuri instead reduces your server load via caching and filtering bot traffic.

DDoS protection included: DDoS attacks can take small sites on shared hosting offline. Sucuri's network absorbs these attacks. Your hosting stays online because traffic never reaches your server. This alone can justify the cost for sites that are DDoS targets.

Hidden server IP: Through DNS routing, your real server IP isn't publicly visible. Attackers can't directly target your server. This prevents bypassing the firewall by hitting the server IP directly.

Blacklist monitoring and removal: Getting blacklisted is catastrophic for your traffic. Sucuri monitors all major blacklists and helps with removal process. This can save weeks in recovery after a hack because removal requests are complex.

CDN bonus: You get a content delivery network free with the firewall. This speeds up your site especially for international visitors. The CDN pays for itself in better user experience and Google Core Web Vitals scores.

Cons:

Expensive compared to plugins: €199 per year for Basic is significantly more expensive than Wordfence Premium (€119). For multiple sites, this quickly becomes expensive without multi-site discount. Budget-conscious sites may find Sucuri too pricey.

Requires DNS control: You must be able to change your nameservers or set CNAME records. Some hosting providers or free services don't give full DNS control. In those cases, you can't use Sucuri.

Extra latency hop: Traffic goes through Sucuri's servers before reaching your hosting. This theoretically adds latency. For most sites, the CDN compensates for this, but very low-latency applications might notice delay.

Third party sees your traffic: All requests and responses go through Sucuri. For sites with privacy-sensitive data, this is a consideration. You trust Sucuri with potentially sensitive information. Their privacy policy is transparent but it remains a third-party.

Basic plan limited cleanup: The cheapest plan has malware removal but not unlimited. If you get hacked multiple times in a year, extra cleanup costs can add up. Platform plan with unlimited removal is therefore often better.

Less deep inspection: Cloud firewalls only see headers and URL parameters. They can't inspect as deeply as endpoint firewalls with access to POST data and database queries. For very complex attacks, this is a limitation.

Setup complexity: Changing DNS is intimidating for non-technical users. If you do it wrong, your site can go offline. Plugins like Wordfence are just install and activate. Sucuri requires more setup knowledge.

Sucuri plugin features (free)

The free Sucuri Security plugin is available to everyone in the WordPress repository, regardless of whether you pay for the cloud service. The plugin offers useful security hardening and monitoring features.

Security hardening options

The plugin can harden your WordPress installation with one-click fixes. It updates file permissions to safe values (644 for files, 755 for directories). It removes WordPress version info from your HTML to complicate version fingerprinting for attackers.

PHP execution in the uploads directory is blocked via .htaccess rules. This prevents uploaded PHP files from being executed – a commonly used attack vector. Theme editor and plugin editor in WordPress admin can be disabled to prevent hacked accounts from modifying code.

The plugin can also add security headers like X-Content-Type-Options, X-Frame-Options, and X-XSS-Protection. These headers instruct browsers to block certain attack types like clickjacking and MIME sniffing attacks.

Audit logging

Sucuri logs all important events in WordPress: logins, logouts, plugin activations, post updates, setting changes, etc. This audit trail is invaluable for troubleshooting and forensics. If something goes wrong, you see exactly what happened and who did it.

Logs show username, IP address, timestamp, and action. You can filter by user, event type, or date range. For sites with multiple admins, this provides transparency about who does what. After a hack, it shows which account was compromised.

Logs are stored locally in your database. For longer retention, you can export them or use a separate logging service. The free plugin keeps logs for 6 months, after which old entries are automatically deleted.

Who is Sucuri suitable for?

Sucuri is ideal for site owners who want peace of mind without becoming security experts themselves. If the idea of troubleshooting a hacked site yourself fills you with dread, Sucuri's cleanup service is worth gold. It's security insurance – you pay for help when things go wrong.

Professional sites and webshops benefit excellently from Sucuri Platform. The €299 per year is cheap compared to revenue loss from downtime. A webshop doing €10k/month loses €333 per day if it's offline. Sucuri's 6-hour cleanup can prevent thousands of euros in downtime.

Non-technical site owners appreciate Sucuri's managed approach. You don't need to understand how firewalls work or update malware signatures. Sucuri does all this. The dashboard is simple with clear graphs of blocked attacks and traffic statistics.

Agencies managing client sites can resell Sucuri. Sucuri has partner programs where you make margin on sold licenses. You can offer Sucuri white-label as your own security service.

Less suitable for

Budget-conscious hobbyists and personal blogs probably find Sucuri too expensive. For a blog without revenue, €199 per year is a lot of money. Free plugins like All In One WP Security or Wordfence free are better options.

Very technical users who like DIY troubleshooting may not need Sucuri's cleanup. If you're comfortable with SSH, databases, and malware analysis, you can do cleanup yourself. In that case, you're mainly paying for the firewall and DDoS protection.

Sites already behind Cloudflare get overlap. Cloudflare also offers a firewall and DDoS protection. You're then paying twice for similar features. Cloudflare's WAF is more technical to configure but can replace Sucuri for advanced users.

Privacy-critical sites may object to Sucuri seeing all your traffic. For sites requiring HIPAA or other strict compliance, you must review Sucuri's architecture with your compliance officer.

Alternatives to Sucuri

Sucuri's unique value is in combining cloud firewall with cleanup services. Alternatives often offer one or the other but rarely both. Here are three options with different trade-offs.

Wordfence

Wordfence is an endpoint plugin that runs on your own server. The big difference: no cleanup services. Wordfence detects malware but you must clean up yourself or hire an expert. The plugin is free with premium for €119/year for real-time updates.

Wordfence burdens your server but needs no DNS changes. Setup is simpler – just install and activate. For technical users who can do cleanup themselves, Wordfence is cheaper than Sucuri.

Choose Wordfence if: You're on a budget, are technical, don't need cleanup services, or don't have DNS control.

Cloudflare

Cloudflare offers a free CDN with basic DDoS protection. Their paid WAF (from $20/month) blocks web attacks similar to Sucuri. Cloudflare is more technical to configure but very powerful for advanced users.

The big miss: no WordPress-specific features or malware cleanup. Cloudflare is platform-agnostic. You configure firewall rules manually. For developers, this is flexibility; for non-technical users, this is complex.

Choose Cloudflare if: You're technical, want WordPress-agnostic security, or already use other Cloudflare services.

MalCare

MalCare combines cloud scanning with one-click malware removal. It's cheaper than Sucuri (from €99/year) and also offers cleanup. MalCare's firewall is however basic compared to Sucuri. No DDoS protection or CDN.

MalCare is a good middle ground between Wordfence and Sucuri. Cheaper than Sucuri but with cleanup that Wordfence lacks. The firewall is however weaker than both alternatives.

Choose MalCare if: You want cleanup services but find Sucuri too expensive, or prefer a plugin over DNS routing.

Frequently asked questions

What does Sucuri cost per month?

Sucuri's Basic plan costs €199 per year, approximately €16.60 per month. The Platform plan is €299 per year (€24.90/month). Sucuri charges annually, no monthly payments. There's a 30-day money-back guarantee if the service doesn't suit you.

Does Sucuri slow down my website?

Sucuri theoretically adds an extra hop between visitors and your server, but the built-in CDN usually compensates for this. For most WordPress sites, Sucuri is neutral to faster through caching. Very low-latency applications might experience minimal delay (10-50ms extra). Test with GTmetrix before and after to measure the impact for your site.

Can I combine Sucuri with Wordfence?

Technically you can use both – Sucuri as cloud firewall and Wordfence for malware scanning at server level. Both firewalls can co-exist because they work at different layers. This is however redundant and expensive. Choose one solution. Sucuri's cloud approach or Wordfence's endpoint approach, not both.

Does Sucuri automatically clean my site?

No, cleanup is not automatic. You must open a support ticket when malware is detected. Sucuri's team then analyzes your site and performs cleanup. This is a manual process because every hack is unique. Automated cleanup risks data loss or incomplete removal of backdoors.

Does Sucuri work with all hosting providers?

Yes, Sucuri works with any hosting because it runs at the DNS level. Your hosting only sees traffic Sucuri allows through. The only requirement is that you can change DNS nameservers or set CNAME records. This is possible with all major providers like TransIP, Antagonist, Vimexx, and ONE.com. Some free hosting services don't give DNS control – Sucuri doesn't work there.
