Cybersecurity & Zero Trust
Security engineered in — verified continuously.
SIS supports security architecture, zero-trust adoption, identity and access management, vulnerability management, and compliance documentation — grounded in evidence and continuous verification.
Zero trust architectureIdentity & access managementVulnerability managementSecurity monitoring & logging
Overview
Security engineered in — verified continuously.
Security is strongest when it is designed into systems and verified like any other requirement. SIS applies an engineering and assurance lens: understand the threats, implement layered controls, and prove they work with evidence.
Zero trust shifts security from network perimeters to identities, devices, and data — every request verified, every access least-privilege.

Questions
Frequently asked.
Where should a zero trust effort start?
Usually with identity — strong, phishing-resistant authentication and least-privilege access — followed by device visibility and segmentation. A maturity assessment sets the order.
Can you help with an ATO?
Yes. We support documentation, control implementation evidence, POA&M management, and continuous monitoring. Authorization decisions remain with the authorizing official.
Do you perform penetration testing?
We coordinate and validate security testing and can partner with specialized penetration-testing firms where independent offensive testing is required.
Do you support CMMC preparation?
We can help contractors understand NIST SP 800-171 requirements and prepare documentation and controls; formal certification is performed by authorized assessors.
