WordPress security that actually works
Generic WAFs and virtual patches don’t stop vulnerability exploits
Patchstack works with all popular webhosts
Your hosting customers are under attack right now
Of 7,966 new WordPress vulnerabilities discovered in 2024, 96% target plugins – completely invisible to WAFs. WAFs only see traffic, not context. WordPress logic sits outside their visibility – and that’s where attackers strike.
The result
Compromised sites, emergency patching, and customer churn.
The solution
Application-layer protection that understands WordPress from the inside out.
“In the first month, Patchstack has blocked 631.5k+ threats across sites using WP Umbrella. We also converted 4.5% of sites to our Patchstack-powered add-on, creating an additional revenue stream.”

Founder of WP Umbrella
Enterprise performance proven at scale
Most WordPress security tools miss the application layer, where almost all attacks happen. Patchstack fixes this with real-time, context-aware protection that understands WordPress from the inside out.

The result
99% fewer false positives, 94% fewer security incidents, and $39K annual savings per dev team. Implementation takes 4 weeks with zero infrastructure changes.
Proven across 50,000+ WordPress installations
Patchstack delivers exceptional performance, maintaining lightning-fast response times that consistently stay under 0.11ms when deployed on PHP 8+ environments. Memory usage remains very low at under 2MB per installation, with the added benefit of linear scaling as your infrastructure grows. Even during peak traffic periods, CPU overhead stays at below 0.1%.
What sets Patchstack apart from traditional pattern-based WAFs is its accuracy, achieving false positive rates of under 0.01% compared to the industry standard of 5-15%. This means legitimate traffic flows seamlessly while genuine threats are effectively blocked. Patchstack maintains a robust 99.9% uptime SLA backed by global redundancy infrastructure, providing the dependable protection your business demands.
System requirements
- PHP 7.4+ (8.0+ recommended)
- <2MB memory per WordPress installation
- MySQL 5.6+ / MariaDB 10.0+
- Outbound HTTPS only
- All major hosting platforms supported
Why network-level security fails for WordPress
Traditional WAFs see HTTP traffic but miss WordPress context. Consider this scenario:
What your WAF sees
Identical HTTP POST to admin-ajax.php with file data
Reality
One is legitimate maintenance, one is a compromise in progress
Your WAF's response
Either blocks both (breaking customer sites) or allows both (missing attacks)
This isn't a configuration problem. It's an architectural limitation.
Network-level firewalls see these requests as identical:
- Same HTTP endpoints (/wp-admin/admin-ajax.php)
- Similar payload structures (action parameters and file data)
- Matching request headers and authentication cookies
But they can't distinguish context:
- What permissions does this user actually have?
- Is this plugin version vulnerable to this specific attack?
- Should this file type be allowed for this user?
- Is this part of a legitimate admin workflow?
Common false positive scenarios include:
- Theme customizations get blocked as "code injection"
- Plugin updates look like malicious file uploads
- Normal content management triggers "SQL injection" alerts
- Media uploads appear to be backdoor attempts

How application-layer protection works
Context-aware protection:
- Each WordPress installation gets isolated protection that won't interfere with other sites
- User sessions are tracked across your entire infrastructure in real-time
- Integrates with enterprise SSO and RBAC systems you're already using
- Context caching keeps latency under 0.11ms
Software Composition Analysis
We scan every WordPress site to identify installed plugins, themes, and core versions, then match against known vulnerabilities to deploy targeted protection where needed.
Patchstack continuously tracks:
- WordPress core versions and update status
- Every active plugin with precise version numbers
- Theme details, including customizations
- Database schemas analyzed for configuration vulnerabilities
Virtual patching architecture
Virtual patches operate at the application layer to prevent exploitation without modifying core WordPress files or plugin code.
When we detect a vulnerability, we develop a virtual patch, test it, and deploy it automatically to affected sites, usually within minutes.
“Over the last 6 months, Patchstack has protected our users from 1.3 million vulnerabilities.”

Remember, if your WAF can’t see it, it can’t stop it. Let’s fix that.
