Security testing shouldn’t be this broken.<br>€Enterprise firms charge €15,000+<br>You get a junior tester following a checklist, an account manager who can’t answer technical questions, and a 200-page PDF six weeks later. Half the findings are informational padding.
⚙Automated scans miss what matters<br>Nessus and Qualys find missing headers and outdated libraries. They don’t find broken authorization, business logic flaws, or the config file that leaks your database password.
?Bug bounties are unpredictable<br>No guaranteed coverage, no compliance-ready report, no timeline. You might get a critical finding in a week or hear nothing for six months. And you still need a pentest report for SOC 2.
✦AI tools miss your business logic<br>An LLM can spot a textbook XSS. It can’t chain a broken access control with your multi-tenant data model to prove a customer-data leak, and no auditor will accept "we asked an AI" as a SOC 2 or ISO 27001 pentest report.
There’s a better way. Faultline Security gives you manual, expert-level testing with a clear scope, fixed price, and a report your auditors will accept.
