Offensive security
Simulating real attacks: from web and infrastructure pentests and physical access attempts to AI-powered Red Teaming.
IT Security: one step ahead of attackers
Penetration testing, Red Teaming and continuous monitoring from EASM to Zero-Day and Dark Web monitoring: how to know your attack surface, validate vulnerabilities and detect attacks before damage occurs.
Effective IT security is not built on individual tests but on the triad of offensive validation (Pentesting, Red Teaming, Bug Bounty), continuous detection (EASM, Zero-Day and Dark Web monitoring, MDR) and organizational response capability (incident response, crisis exercises, audits). These knowledge pages bundle our methodology along exactly these three axes — including our own platforms such as VamiRedteam and a 24/7 managed service model.
Topics & knowledge pages
Each topic leads to a dedicated knowledge page with deep dives, practical guides and the matching services.
Monitoring & detection
Continuously see your own attack surface — and detect attacks before they take effect: EASM, Zero-Day, Dark Web, MDR.
Organization & resilience
Audits, Threat Modeling, incident response and crisis exercises — so an emergency does not turn into chaos.
IT Security Architecture
The building blocks that carry security over the long term: cryptography, trust anchors, and key management — starting with the migration to post-quantum cryptography.
Deep Dives
In-depth knowledge pages on the topics that currently raise the most questions — with verified sources and concrete measures.
Post-Quantum Cryptography
Quantum computers will break RSA and elliptic curves — and “Harvest now, decrypt later” already makes long-lived data vulnerable today. This page explains the threat, the standards, the deadlines, and the migration program: from the Mosca test through the EU roadmap 2030/2035 and BSI TR-02102-1 to cryptographic inventory, CBOM, and crypto-agility.
View knowledge pageData Loss Prevention
How to systematically prevent the uncontrolled outflow of sensitive data — from data classification through policy design in Microsoft Purview to well-governed operations.
View knowledge pagePrivileged Access Management
Privileged accounts are the shortest path to compromising entire environments. PAM governs their provisioning, use and monitoring across governance, architecture and operations - VamiSec supports design, rollout and ongoing operation.
View knowledge pagePenetration Testing
How a penetration test works, how it differs from vulnerability scans and red teaming – and which methodologies, processes and regulatory requirements matter when commissioning one.
View knowledge pagePhysical Pentesting
How access controls, building processes and on-site behaviour can be verified under realistic attack conditions – controlled, authorised and documented in a traceable way.
View knowledge pageIoT Penetration Testing
Connected products are not pure software systems: they consist of a circuit board, firmware, radio links, a cloud backend and an app. An IoT penetration test examines these layers as a coherent whole – exactly where attackers take hold.
View knowledge pageRed Teaming
How targeted simulations modelled on real-world adversaries let you verify whether your organisation actually detects, contains and responds to an attack – not just whether a single vulnerability exists.
View knowledge pageMITRE ATT&CK
Since 2015, MITRE ATT&CK has documented publicly observed tactics, techniques and procedures (TTPs) of real-world adversaries. We show how to use the framework for detection engineering, threat intelligence and red teaming – and where its limits lie.
View knowledge pageBug Bounty & VDP
How to receive, process and reward vulnerability reports from external security researchers in a structured way – from a vulnerability disclosure policy to a private bug bounty program.
View knowledge pageEASM
How continuous discovery from an attacker's point of view makes unknown assets, shadow IT and exposed services visible – from initial detection all the way to remediation.
View knowledge pageVulnerability Management
How to steer technical vulnerabilities across their entire lifecycle – and use CVSS 4.0, EPSS and the CISA KEV catalog to close the gaps that are actually under attack first.
View knowledge pageDark Web Monitoring
How to detect compromised credentials, mentions of your company and data leaks before attackers exploit them – and where the limits of the approach lie.
View knowledge pageAttack Detection
How to implement the obligation to deploy attack detection systems under § 31 BSIG in a structured way – from the BSI guidance through log sources and detection engineering to the required evidence.
View knowledge pageMDR
How to position Managed Detection & Response, choose the right operating and provider model, and integrate the service cleanly into your security organization – from log source onboarding to the SLA.
View knowledge pageCompromise Assessment
How forensic methods give you a reliable answer to whether your IT environment is currently compromised or was compromised in the past – and what consequences follow from that.
View knowledge pageHoneypots & Deception
How honeypots, honeytokens and deception platforms help you detect attackers inside your internal network early – with high signal quality and, by design, very few false positives.
View knowledge pageIT Security Audits
How technical security audits and compliance audits work together – from Active Directory to M365, firewalls and architecture, assessed against CIS Benchmarks, vendor baselines and BSI IT-Grundschutz.
View knowledge pageM&A Due Diligence
How to reliably assess the cyber security posture of an acquisition target under time pressure – and what the findings mean for purchase price, warranties and integration.
View knowledge pageIncident Response
How organisations detect, contain and investigate security incidents in a structured, court-admissible way – and which reporting deadlines run in parallel.
View knowledge pageCyber Resilience & BCM
How to safeguard the continuity of your critical business processes with BSI Standard 200-4 and ISO 22301 – from the business impact analysis and backup strategies to crisis team exercises.
View knowledge pageOT & Industrial Security
How to systematically secure industrial control and automation systems – from IEC 62443 zones and security levels through the Purdue model to the NIS2 obligations for manufacturing.
