The academic literature and vendor whitepapers on Zero Trust Network Access (ZTNA) are replete with theoretical security models, but as a practitioner whose primary metric is operational efficiency—where security failures represent the ultimate cost overrun—I am inherently skeptical of claims untested by adversarial simulation. My organization is conducting a preliminary architecture review for a ZTNA implementation, with Banyan Security as a leading contender. However, before any procurement committee can be approached, a rigorous evidence-based assessment is required.
Consequently, my core inquiry is empirical: **Has any independent security team executed a genuine penetration test or red-team engagement against a production or lab environment protected by Banyan's ZTNA framework?** Vendor-sponsored assessments, while useful for compliance checklists, lack the adversarial context of a true pen-test. I am seeking detailed, concrete observations from the community that move beyond marketing assurances.
Specifically, I am interested in the technical particulars of such an engagement, which would greatly inform our own testing scope. For instance:
* **Testing Methodology & Scope:** Was the test black-box, gray-box, or white-box? What was the defined attack surface (e.g., the end-user device, the Banyan client/connector, the Trust Registry, the policy engine)?
* **Identity & Device Trust Assumptions:** How robust were the conditional access policies under test? Were attempts made to subvert device trust scores or present forged certificates from registered devices?
* **Lateral Movement Prevention:** Once initial access to a single application was (theoretically) achieved, did the micro-tunneling and default-deny posture effectively contain lateral movement within the private network, as claimed?
* **Tooling & Evasion:** Did standard pen-testing tools (e.g., Metasploit, Cobalt Strike) require significant modification to operate within the ZTNA tunnel, or were network-based attack patterns effectively neutralized?
Anecdotal evidence of "no critical findings" is less valuable than the procedural narrative of the test itself. For example, a finding might not be a direct vulnerability in Banyan, but a configuration pitfall that a test revealed, such as an over-permissive access policy that emerged during testing. Sharing any sanitized excerpts from test reports, or even the testing rules of engagement, would be immensely valuable.
In my domain, we treat security controls as infrastructure with a recurring operational cost. The efficacy of these controls directly impacts financial risk. Therefore, understanding the practical, tested security boundary of a proposed ZTNA solution is a non-negotiable prerequisite for its total cost of ownership analysis. Any shared experiences will contribute significantly to a more secure and financially responsible architecture selection.
