Network penetration testing from the attacker's vantage point.

External attack surface enumeration, internal host discovery, credential attacks, lateral movement, and segmentation checks — end-to-end infrastructure coverage.

What we test

Full coverage, tested by hand.

Every assessment is led by an OSCP- or CREST-certified tester — not a scanner with a human proofreading the output.

External attack surface mapping

Full-scope enumeration of internet-facing services: open ports, service versions, exposed management interfaces, and subdomain attack surface.

Service & version exploitation

Identify outdated service versions with known CVEs and validate exploitability under your actual patch level and configuration.

Credential attacks & lateral movement

Password spraying, credential stuffing, Kerberoasting, pass-the-hash, and lateral movement paths mapped across the internal network.

Segmentation & firewall validation

Verify that network zones are isolated as intended — testing whether a breach in one segment can reach your crown jewels in another.

Methodology

How we run the engagement.

A structured process that ends with a report you can hand directly to your auditor.

1
Reconnaissance

Passive OSINT and active scanning to map the full external attack surface before any exploitation attempt.

2
Vulnerability identification

Port scan, service fingerprint, CVE cross-reference, and misconfiguration checks across all in-scope hosts.

3
Exploitation

Manual exploitation of confirmed vulnerabilities — no false positives from automated scanners alone.

4
Post-exploitation

Lateral movement, privilege escalation, data extraction proofs of concept, and domain dominance simulation.

Sample findings

The kind of issues we find.

Real finding types from past engagements — titles and targets anonymised.

criticalCVSS 9.8SB-N-001
Unauthenticated RCE via EternalBlue on legacy host
10.0.0.47:445 (Windows Server 2008 R2)Day 1
Remediation — Patch MS17-010 immediately. Isolate legacy systems that cannot be patched behind strict firewall rules with no lateral reachability.
highCVSS 8.1SB-N-002
Domain admin achieved via Kerberoast + weak password
corp.acme.local — SVC_BACKUP accountDay 2
Remediation — Enforce 25-character minimum on all service account passwords; audit SPNs and remove unused ones. Enable AES encryption for Kerberos.
mediumCVSS 5.9SB-N-003
Production VLAN reachable from guest WiFi segment
VLAN 10 → VLAN 40 firewall policyDay 3
Remediation — Review and tighten inter-VLAN ACLs. Block all traffic from guest/untrusted networks to production segments at the distribution layer.
Platform

Findings land live — not in a PDF three weeks later.

Every confirmed issue goes into the platform the moment it's documented. Your team tracks status, chats directly with the tester, and exports evidence without waiting for the engagement to close.

Live findings during testingIssues appear as they are confirmed — no batch delivery at the end.
Direct tester chatComment on any finding and the tester who wrote it responds.

FAQ

Questions about this service.

Still unsure? Ask an engineer in chat — not a sales rep.

Both are available. External tests assume an internet attacker. Internal tests start from a foothold inside your network (VPN access or on-site).

Know where you stand before your auditor does.
