Offensive security.

Proactive testing that exposes risks before they’re exploited.

–01

Vulnerability assessments.

Find and understand your organization’s security weaknesses. Effectively discover missing security patches, default credentials, or other misconfigurations before malicious actors do. Vulnerability scanning can often be used as a precursor to a full penetration test where the discovered flaws are verified through exploitation.

Who needs it?

Organizations that want to improve their security and/or meet compliance requirements without performing vulnerability exploitation.

What we do

A dedicated semi-automated software analyzes each target host to identify services and check against a database of tens of thousands of known security vulnerabilities (CVEs) to see if the systems are potentially affected.

Tools we use

Vulnerability Assessment – Nessus Professional

Traffic interception and manipulation – Burp Suite Professional

Port and Service discovery – Nmap

Directory & endpoint enumeration – Dirb/Wfuzz/Ffuf

API interaction – Postman

Deliverables

You will receive a detailed report highlighting the present vulnerabilities – all with assigned risk ratings (CVSS calculated) and remediation steps.

–02

Penetration testing.

Challenge your defenses with an exploitative highly-technical assessment to identify and validate vulnerabilities. Regardless whether you are looking to test your web or mobile applications, your network or infrastructure, we are here to show you what you’ve missed. We can test anything ranging from web and mobile applications to networks, API’s, LLM’s and your network segmentations.

Who needs it?

Organizations that want to improve their security stance and/or achieve compliance.

What we do

  • Plan with you

  • Search through open-source intelligence

  • Scan for open ports, running services, and vulnerabilities

  • Manually look into each target in great details

  • Exploit and chain attack vectors

  • Both unauthenticated and authenticated testing

  • Clean up

Tools we use

Vulnerability Assessment – Nessus Professional

Traffic interception and manipulation – Burp Suite Professional

Port and Service discovery – Nmap

Directory & endpoint enumeration – Dirb/Wfuzz/Ffuf

API interaction – Postman

Deliverables

You will receive a clear and polished report containing but not limited to:

  • Executive Summary

  • Findings – detailed description, risk level (per CVSS), remediation suggestions, evidence, and steps to reproduce/exploit.

  • Technical Narrative

–03

Red/Purple teaming exercises.

Red and Purple Teaming exercises are where theory meets reality. Our experts think like attackers, probing your technological and human defenses to uncover blind spots before adversaries do. But there’s no need to stop at breaking in. We can work side by side with your defenders, sharpening their response and closing the gaps. It’s not just a test, it’s a rehearsal for the threats that haven’t happened yet.

–04

Social engineering.

Are your employees ready to withstand a campaign meant to manipulate and exploit human errors through deception? These techniques are used by hackers to gain sensitive data or plant ransomware. We will manually test your security awareness through a custom email phishing setup or tailored vishing scripts. You will receive a detailed report on how your employees did, alongside with recommendations on how to manage your human risk.

–05

Segmentation testing.

PCI DSS requirement 11.3.4 expects annual validation that segmentation controls effectively isolate all out-of-scope systems from the cardholder data environment (CDE). PCI guidance requires connections to the hosts in the CDE segment to be blocked if segmentation has been used to isolate the CDE from other networks.

Who needs it?

Organizations seeking to achieve or maintain PCI DSS compliance.

What we do

As a standalone service or a part of a penetration test, we perform segmentation testing through port and service scanning to determine whether it was possible to access the CDE from a non-CDE network.

Review of firewall rules

Review Network architecture diagram and communication workflow

Network scan from each network segment leveraging pentest tools such as NMAP

Vulnerability scan for each network segment

Deliverables

You will receive a comprehensive report with results showcasing whether the segmentation controls and methods effectively isolate the hosts dealing with cardholder data.

–06

LLM testing.

Large Language Model Testing is about exposing the hidden risks of deploying AI at scale. We dig into the blind spots of LLM applications, uncovering critical vulnerabilities like prompt injections, data leakage, weak sandboxing, and unauthorized code execution. Our goal is simple: show you how these flaws can be exploited, measure their real-world impact, and help you harden your AI before attackers weaponize it.

Who needs it?

Any company that has implemented some sort of LLM in their product line or services.

What we do

We will attempt a series of penetration tests on all LLMs in scope to identify potential vulnerabilities related to their implementation. Based on OWASP Top 10 for LLM, we will then generate a detailed report of our findings, including a criticality score, remediation steps, and details. We will discuss this with you and assist you with remediation advice from our experts.

Deliverables

You will receive a comprehensive report with results showcasing whether the LLM was implemented correctly and whether we have identified ways to exploit it for malicious purposes.
