Every configuration change, firmware update, and protocol feature that gets enabled on a network device shifts the security surface. Most of the time, the shift is small. But those small shifts accumulate, and without regular, targeted testing, you end up with a security posture that looks nothing like what you designed. Default credentials left open, unnecessary services running, ACLs that don't match the policy, management interfaces exposed on the wrong VLANs. These are the kinds of things that slip through.
We run security assessments focused specifically on network devices and perimeter controls. Not generic vulnerability scans. Targeted testing of the things that actually matter in a networking environment. Access control validation, management plane hardening, protocol-level security (BGP MD5, OSPF authentication, SNMP v3 enforcement), firmware vulnerability checks, and configuration drift analysis.
What you get back is specific to your environment. Not a 200-page report full of CVEs to triage, but a focused set of findings with clear remediation steps your engineering team can actually execute.
