Network Security Testing
Layered network assessment covering firewall rules, segmentation, and protocol-level weaknesses.
Security testing
In plain terms Testing
What this is
Layered network assessment covering firewall rules, segmentation, and protocol-level weaknesses.
Why it can hurt you
Firewall rulesets accrete over years; "temporary" allow rules from three reorganizations ago are still open today.
Security testing
Why it matters to you Testing
The problem
Firewall rulesets accrete over years; "temporary" allow rules from three reorganizations ago are still open today.
Reduced lateral risk
Confirm segmentation actually contains a breach.
Audit-ready evidence
Rule review doubles as PCI DSS segmentation testing evidence.
Security testing
How we do it Testing
Firewall & ACL review
Rule-by-rule audit for overly permissive or stale entries.
Segmentation testing
Verify zones actually enforce the isolation the network diagram claims.
Protocol-level testing
VLAN hopping, ARP spoofing, and routing-protocol abuse where in scope.
Security testing
What we typically find Testing
Overly permissive rules
Any-any rules or overly broad port ranges left from past projects.
Segmentation gaps
Zones that appear isolated on paper but route freely in practice.
Insecure management protocols
Telnet, unencrypted SNMP, or default credentials on network gear.
No scanner dump. A fixed problem.
Every finding is reproduced by hand and comes with a working proof of concept.
Security testing
What lands on your desk Testing
Rule audit report
Every rule flagged clean, risky, or needs-removal.
Segmentation diagram
Actual vs. intended traffic flow, side by side.
Security testing
What you get out of it Testing
Reduced lateral risk
Confirm segmentation actually contains a breach.
Audit-ready evidence
Rule review doubles as PCI DSS segmentation testing evidence.
Security testing
Step by step Testing
1. Firewall & ACL review
Rule-by-rule audit for overly permissive or stale entries.
2. Segmentation testing
Verify zones actually enforce the isolation the network diagram claims.
3. Protocol-level testing
VLAN hopping, ARP spoofing, and routing-protocol abuse where in scope.

A scoping call is thirty minutes, costs nothing, and ends with a fixed price and a date. If we are not the right people for the job, we will tell you that too.
