PENETRATION TESTING

Penetration Testing

See your network through an attacker’s eyes

Automated scanners find known issues, but they rarely think like a real adversary. Karhu Cyber’s offensive security engagements go further. Our testers chain together misconfigurations, exposed services, and weak controls the same way modern attackers do, including the AI-assisted techniques adversaries now use to move faster and at greater scale.

Whether you need a tightly scoped penetration test against a specific application or network, or a full red team engagement that emulates a sophisticated, goal-driven adversary across your people, processes, and technology, we tailor the work to your environment and your objectives. Every assessment is scoped around the risks that matter most to your business, not a generic checklist.

What sets our testing apart is that it does not happen in a vacuum. Every engagement is fed in real time by our blue team, whose continuous monitoring keeps them informed on current threat activity and the live state of your environment. This purple team approach lets our offensive operators attack with the same intelligence your defenders are seeing day to day, so the techniques we use reflect what is actually targeting organizations like yours right now. The result is testing that is sharper, more relevant, and immediately actionable for the people defending you.

We surface the threats that count: Active Directory misconfigurations, exposed services, inadvertently exposed sensitive data, and the privilege escalation and lateral movement paths that let a single foothold become a full compromise. Every engagement ends with a clear, individualized report that explains what we found, how we found it, and exactly how to fix it, written so both your executives and your engineers can act on it with confidence.

Go on the offensive

We test your readiness against the latest real-world tactics, techniques, and exploit paths, including:

  • Active Directory and identity attacks
  • Network spoofing and traffic interception
  • Exploitation of misconfigured and weakly credentialed systems
  • Privilege escalation and lateral movement
  • Data exposure and exfiltration paths
  • AI-assisted reconnaissance and attack automation

Our penetration testing services

Targeted, adversary-driven assessments across every layer of your environment.

Network

We attack your internal and external networks the way a determined adversary would, chaining together exposed services, misconfigurations, and weak credentials to reach your most sensitive systems. You get a clear picture of your real attack surface and the prioritized fixes that close it.

Web App

Modern breaches often start with a single insecure web application. We go beyond automated scanners to manually probe authentication, authorization, business logic, and APIs, then deliver tailored, developer-ready guidance to remediate every finding.

Wi-Fi

Wireless networks are a frequent blind spot and an easy entry point. We assess your Wi-Fi for weak encryption, rogue access points, and segmentation gaps to ensure a compromised wireless client cannot become a path into your core environment.
