Solutions / Penetration Testing
Penetration Testing
Find the vulnerabilities attackers would, before they do. Methodical, expert testing of your network, applications, and people, with a clear, prioritized report and a fix plan, plus a retest to verify. Remote-first, nationwide.
Test like an attacker, report like a partner
We probe the same paths attackers use, then hand you a plan you can act on.
External network testing
Test your internet-facing systems the way an outside attacker would.
Internal network testing
Simulate a breached device or insider to find lateral-movement risk.
Web & application testing
Find the flaws in your web apps and portals before attackers exploit them.
Phishing & social engineering
Test how your team responds to realistic phishing and pretext attacks.
Wireless testing
Assess Wi-Fi for rogue access, weak segmentation, and exposure.
Reporting & remediation
A prioritized report, an executive summary, and help fixing what we find.

Frequently asked questions
How is a pen test different from a vulnerability scan?
A scan lists potential issues automatically. A penetration test has experts actually attempt to exploit them, showing real-world impact and what matters most.
Will testing disrupt our operations?
No. We scope and schedule testing to be safe, and coordinate closely so day-to-day work is not affected.
Do you help fix what you find?
Yes. We prioritize the findings and help you or your IT team remediate, then retest to verify.
How often should we test?
At least annually, and after any major change to your network, applications, or locations.
