WordPress is the top dog among CMSs - worldwide! The interest of cyber criminals is correspondingly high. A quick WordPress security audit can quickly help to close security gaps and minimize the attack surface.
What we test in WP projects
Code review for custom developments, combinations of premium themes and security plugins.
WooCommerce, member portals, API integrations - including permission and payment protection.
Validation of deployment processes, staging environments and backup strategies.
WordPress is often the public face of your business - with custom themes, integrations and a plugin ecosystem that few other systems can match. This very flexibility creates attack surface: An unpatched extension, poorly implemented role models or an orphaned plugin are enough to compromise customer data, campaigns and brand trust.
Identify shadow IT We test which plugins, cronjobs and REST endpoints are running in production - including dependencies that don't appear in any ticket system.
Secure business logic WooCommerce, headless setups or membership portals: we test payment flows, account takeovers and content moderation for real exploits.
Compliance & Reputation GDPR, agency contracts or corporate policies require verifiable security testing before releases go live.
We deliver prioritized findings with PoCs, clear recommendations for developers and - if desired - management summaries for stakeholders. This way you maintain control over your digital storefront and avoid emergency responses mid-launch.
We combine technical testing with operational hardening so your team can start implementing immediately. We work closely with developers, agencies and hosting teams - remotely or on-site.
Kickoff & Baseline Scope workshop, architecture check and deployment review - including scans for already compromised assets.
Hardening sprints Implementation recommendations for authentication, logging, WAF, backups and monitoring - tailored to your toolchain.
Enablement Playbooks, pairing sessions and training for editors, developers and hosting teams.
We offer two testing formats - depending on whether you need a quick security baseline or a comprehensive audit with hardening.
For content sites & microsites
For business-critical WordPress

A large part of the internet is based on websites and web applications.
Modern websites and SPAs usually communicate with some kind of API.
Fully automated vulnerability scanning for your IT infrastructure or application.
WordPress is often your most important marketing or sales channel. When themes are extended, plugins combined and interfaces integrated, the attack surface grows dramatically. A WordPress pentest is always worthwhile when downtime equals revenue loss or when compliance requirements demand verifiable security evidence.
Business-critical funnels Shop, lead or membership areas where broken checkout or account flows directly jeopardize revenue, reputation or growth objectives.
Sensitive data & role models Multi-level approvals, custom roles, CRM and ERP integrations - we test access controls, APIs and data leaks for real privilege escalations.
Governance & compliance When auditors, investors or customers expect evidence, we anchor security checks into your release and update processes.
If you answer "Yes" to any of these statements, a targeted pentest including hardening plan usually delivers actionable results within days.
WordPress pentests uncover a wide range of vulnerabilities - from classic web application flaws to WordPress-specific security issues in plugins, themes and core configuration.
A WP pentest is essentially nothing more than a normal web application pentest with PHP focus. Classic vulnerabilities like local file inclusions, SQL injections, authorization bypasses and XSS are part of the standard test scope.
The quality of many WordPress plugins and themes leaves much to be desired. The number of security vulnerabilities is alarmingly high. We often find that sites have already been compromised and PHP shells have been hidden everywhere. We help identify and remove them.
Especially with WordPress, we frequently see incorrect use of AJAX requests. Developers regularly forget to check access rights (capability checks) and nonces, which can lead to unauthorized access and data manipulation.
PHP object injection and insecure deserialization are common problems in WordPress. Especially in older plugins, we regularly find unchecked unserialize() calls that can lead to remote code execution.
Faulty implementations of custom login flows, incorrect use of wp_set_auth_cookie(), or insufficient session validation often allow attackers to completely bypass WordPress authentication.
Insufficient validation of file uploads in custom plugins or themes regularly leads to arbitrary file upload. Missing MIME type checks and insecure path handling enable uploading of web shells.

We've had the privilege of working with some of the world's leading companies and strengthening their IT security.
With WordPress, the focus is more on the technical security of individual components, less on compliance. Accordingly, most WordPress penetration tests are completed in less than 3 days.
With WordPress, the parts to be tested should be available as source code. We also appreciate having a corresponding demo system where we can test thoroughly.
Depending on how important the data in your installation is. At least annually, but better with major changes.
That shouldn't be a problem, as we actually always only test against test systems or perform source code analyses. However, a complete relaunch should not take place during the test.
We discuss all security vulnerabilities and show how to fix them. We are happy to take over the closing ourselves - we have several PHP developers in our team. If required, we can also create a formal report.
