Benefits of working with a penetration testing company like Zero Through
A vulnerability scan tells you what might be wrong. A penetration test tells you what an attacker could actually do about it. Our testers chain small weaknesses together the way real intruders do, then show you the consequence in terms your board understands:
- Find out what is genuinely exploitable, not just what appears on an automated report.
- Satisfy the clients, insurers and auditors now asking for evidence of independent testing.
- Fix the right things first, with findings ranked by business impact rather than raw severity.
- Prove the fix worked, with retesting included rather than quoted as extra.
Testers, Not Scanners
Automated tools have their place, but they cannot chain three minor issues into a full compromise. Our testers do the manual work that finds the problems tools walk past.
Reports You Can Act On
Every finding comes with the evidence, the business consequence and a specific remediation step. Written so your developers and your directors both get what they need.
Retesting Included
Once you have fixed the findings, we verify them at no extra cost. A test that ends at the report leaves you no better protected than before.
Certified and Insured
Testing is scoped carefully, documented clearly and followed by remediation guidance and retesting so your team can act on the findings.
A penetration testing company that stays until it is fixed
Plenty of firms will send you a PDF and an invoice. The report is the easy part — the value is in what happens next, and that is where most testing engagements quietly end:
- A debrief call where we walk your team through the findings and answer questions properly.
- Remediation guidance written for the people who will implement it, not generic advice.
- Free retesting of every fixed finding, so you can evidence closure to clients and auditors.
- A clean summary certificate you can share with third parties without exposing the detail.
Testing scoped to what you actually run
We scope each engagement around your estate and your reason for testing, whether that is a client requirement, a compliance deadline or genuine curiosity about how you would hold up:
Web Application Testing
Authenticated and unauthenticated testing of your applications, covering the logic flaws and access control failures scanners cannot see.
External Network Testing
Everything exposed to the internet assessed the way an opportunistic attacker would find and probe it, from any starting point.
Internal Network Testing
We assume a foothold has been gained, then establish how far it could spread and what an intruder could reach from there.
Cloud Configuration Review
Microsoft 365, Azure and AWS environments reviewed for the permissive settings and exposed storage that cause most cloud breaches.
Mobile Application Testing
iOS and Android applications tested for insecure storage, weak transport protection and flaws in the back-end services behind them.
Wireless Assessment
Your wireless networks tested for weak segregation and rogue access points, including whether guest access truly stays separate.
Social Engineering
Phishing and pretext calling, run to an agreed scope, to establish how your people respond when someone applies pressure.
Retest & Verification
A second round of testing once your fixes are in place, confirming each finding is genuinely closed rather than merely reported as done.
