CHALLENGES

Selecting a Platform to Support a Mature Security Program

After evaluating several offensive security solutions, Stonebranch selected Siemba for its ability to combine penetration testing with vulnerability management through a flexible SaaS subscription model.

Enterprise portfolio management

Risk-based prioritization

AISO insights

Collaborative remediation workflows

MOVING TOWARD CONTINUOUS VALIDATION

As part of this shift, Stonebranch began using Siemba’s Penetration Testing as a Service platform to complement its existing testing approach. This made it possible to identify additional vulnerabilities and move toward a more continuous assessment model. The depth of Siemba’s web application testing provided clearer insights into application security.

Broader vulnerability coverage

Reduced reliance on annual-only testing cycles

THE OUTCOME

Scalable offensive security program

Stonebranch moved from periodic testing toward a more programmatic and proactiveapproach.

Improved visibility

Dashboards provided clearer insight for both leadership and engineering teams.

Smarter prioritization with AISO

Noise was reduced and exploitability became easier to assess, helping teams focus onhigher-priority issues.

Cross-team alignment

Security, engineering, and operations teams worked from a shared process.

More efficient remediation

Detailed documentation and video proof supported faster identification of root causes.

Audit readiness

One-click reporting helped reduce the effort required for audit preparation.

PREPARING FOR WHAT'S NEXT

Stonebranch is adopting a strategy focused on continuous threat detection and validation.

Siemba has introduced upcoming Continuous Threat Exposure Management capabilities, including GenPT for autonomous penetration testing, attack surface mapping, and third-party integrations.

These enhancements are expected to further support Stonebranch’s security posture over time.
