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.
