Technology

Challenge

As Stonebranch’s environment continued to grow and modernize, its approach to penetrationtesting also needed to evolve. While vulnerabilities were being identified, the team wanted greater depth and context to better support prioritization and remediation decisions.

About Customer

Powering Enterprise Automation at Global Scale

Stonebranch delivers IT orchestration and automation solutions that support enterprises as they
evolve from basic task automation to more advanced, real-time service automation. The
platform emphasizes simplicity, modern architecture, and enterprise-grade security,
helping organizations manage workloads and data across a wide range of technologies and
environments.

Asia, serving enterprises in financial services, manufacturing, healthcare, travel,
transportation, energy, and technology.

Evolving Security Needs

“Our main objective was to work with a provider who could deliver comprehensive assessments
and add value to our overall cybersecurity strategy,” said Cinu Varghese, Vice President of
Cloud Operations and Product Support at Stonebranch.

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.

“Siemba’s enterprise-grade penetration testing and vulnerability management approach, along with its easy-to-adopt SaaS subscription model, were important factors in our decision,” said Cinu Varghese.

Capabilities That Supported Security Operations

Stonebranch used Siemba to help operationalize security across teams:

Enterprise portfolio management
Helped organize assets across departments and provided clearer visibility into risk patterns.

Risk-based prioritization
Supported more informed remediation decisions by balancing severity with real-world
exposure.

AISO insights
Helped reduce false positives, assess exploitability, and surface relevant threat indicators.

Collaborative remediation workflows
Enabled security, engineering, and operations teams to work from a shared platform.

One-click reporting
Simplified the creation of executive, compliance, and technical reports.

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.

Observed impact:
✔ Broader vulnerability coverage
✔ Reduced reliance on annual-only testing cycles

Outcomes That Supported Program Maturity

Scalable offensive security program
Stonebranch moved from periodic testing toward a more programmatic and proactive
approach.

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 on
higher-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.

Business Value

Security value

Improved prioritization, remediation workflows, and visibility into risk and timelines.
Organizational value

Improved confidence across leadership and customers, with clearer visibility into security risk at the board level.

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.

“Today’s cyber threats require us to make quick, data-driven decisions. Siemba’s AISO
insights have provided actionable recommendations and have been instrumental in
improving our security program across the enterprise.”
