Professional website security,
accessible to everyone
Pentesterr is a complete web security platform built by security engineers who believe every business — regardless of size — deserves enterprise-grade protection.
Our Mission
To democratise website security by giving every business — from solo developers to enterprise teams — the same vulnerability detection, penetration testing, and continuous monitoring capabilities that were previously only available to large organisations with dedicated security budgets.
What We Do
Pentesterr combines automated scanning, real-time monitoring, and professional reporting into a single platform. Here is what we cover:
WordPress Security Auditing
WordPress powers 43% of the web and is the most targeted CMS by attackers. Our deep-scan engine detects vulnerabilities in WordPress core, plugins, and themes against a database of 20,000+ CVEs — identifying outdated software, exposed admin interfaces, weak configurations, and brute-force risks before they are exploited.
Penetration Testing
Our automated penetration testing engine simulates real-world attacks against your web applications. We test for SQL injection, cross-site scripting (XSS), authentication bypass, open redirects, sensitive data exposure, and all OWASP Top 10 vulnerability categories — giving you a clear picture of your exploitable attack surface.
Vulnerability Assessment
Comprehensive vulnerability assessments that map every weakness in your web stack to industry-standard frameworks including CVE, CVSS, CWE, and OWASP. Every finding is scored by severity so your team always knows what to fix first. Compliance-ready reports help you meet GDPR, PCI-DSS, and HIPAA requirements.
SSL/TLS & Security Header Analysis
Full certificate chain validation, cipher suite grading, HSTS enforcement checks, and HTTP security header auditing. We detect missing Content-Security-Policy, X-Frame-Options, Referrer-Policy, and Permissions-Policy headers — and provide exact remediation steps for each finding.
24/7 Uptime & Change Monitoring
Monitor your sites every 5 minutes from multiple global locations. Receive instant email alerts when your site goes down, a page changes unexpectedly, or a new vulnerability is published for your software stack. Historical uptime reporting keeps you accountable to SLAs.
Real-Time Security Agent
The Pentesterr Security Agent is a lightweight WordPress plugin that streams security events — failed logins, plugin changes, file modifications, user creation, and settings changes — directly to your dashboard in real time. Events are stored off-site so your audit trail is tamper-proof even if your site is compromised.
Malware & Blocklist Detection
Scan for malware signatures, injected scripts, and SEO spam. Cross-reference your domain against Google Safe Browsing, Spamhaus, and 30+ global blocklists. Protect your search rankings and brand reputation by knowing the moment your site is flagged.
Professional Security Reports
Generate branded, client-ready PDF security reports with executive summaries, technical findings, severity ratings, and step-by-step remediation guidance. Perfect for agencies delivering security audits to clients, or businesses demonstrating compliance to regulators.
Our Technology
Pentesterr is built on a modern, cloud-native security scanning infrastructure that combines multiple scanning methodologies with a continuously updated threat intelligence database. Our platform is designed for accuracy, speed, and scale:

Our Story
Pentesterr was founded in 2024 by a team of cybersecurity professionals who recognised a critical gap in the market: while enterprise organisations had access to sophisticated security tooling, small and medium businesses — and the agencies that serve them — were left with either expensive manual penetration testing engagements or superficial free scanners that missed the vulnerabilities that mattered most.
WordPress was the obvious starting point. With over 43% of all websites running on WordPress and a plugin ecosystem of 60,000+ extensions, the attack surface is enormous. Yet most WordPress site owners have no visibility into which of their plugins are vulnerable, whether their admin interface is exposed, or whether someone is actively attempting to brute-force their login page.
We built Pentesterr to change that. Our platform combines automated vulnerability scanning, real-time event monitoring via the Security Agent plugin, professional reporting, and 24/7 uptime monitoring — giving every business the security visibility that was previously only available to organisations with dedicated security teams.
Today, Pentesterr serves thousands of users worldwide — from solo developers protecting their first WordPress site to agencies managing hundreds of client sites and enterprise security teams running continuous compliance programmes.
