Full-Stack Pentest Results Consolidated into One Cloud Platform

BreachLock’s award-winning PTaaS Platform is carefully engineered to give you a high-level, holistic view of your full attack surface in one place with automated workflow integrations that help your DevOps team maximize operational efficiency.


Prioritize DevOps Remediation in Seconds

Digging through findings in reports with little context and guidance is time consuming and redundant – prioritize vulnerability patching by risk that BreachLock determines by referencing industry standards (e.g., OWASP, NIST, etc.) and potential business impact.


Minimize PenTesting Overhead

Maintaining a bunch of best-in-breed security tools restricts bandwidth, which quickly adds to TCO, especially with the increasing scarcity of technical talent. Consolidating all penetration testing exercises with one provider like BreachLock can prevent unnecessary increases in TCO, especially when Jira, Slack, and Trello are included and don’t require additional training hours.


Run Unlimited Automated Retests

We understand how important a clean penetration testing report is for our customers to meet compliance and security regulations, so BreachLock includes a free manual re-test with every penetration test to validate your fixes. Launch unlimited automated re-tests on any automated findings with a single click to validate your patches before the manual retest with confidence that you’ve improved your security posture.


Access 1:1 Remediation Guidance and Customer Support

Penetration testing engagements should never leave you with confusion or unanswered questions - you should never be left in the dark, especially throughout remediation. Get access to 1:1 support from your assigned customer success professional from start to finish.
