Offensive Security
Exploiting Context,
Securing Systems.
Penetration testing, adversary simulation, and offensive research for organizations from startup to enterprise.
Who we are
Lambda Security is a security company dedicated to delivering high-quality penetration testing, offensive security, and adversary simulation services. Our work is entirely offensive, which keeps the focus on how systems actually fail rather than on checklists.
Our team consists of offensive security operators with extensive experience running engagements across diverse industries and organizational scales, from early-stage startups to multinational enterprises. We have worked alongside in-house security teams as well as organizations standing up their first serious testing program.
Every engagement is run by hand. We do not lean on automated scanners, and we do not ship findings a tool could have generated on its own. What you get back is actionable intelligence: each finding prioritized by real-world risk, documented so your team can reproduce it, and set out with the path an attacker would take and what it takes to close it. Reports are handcrafted by the operators who ran the engagement and delivered directly, not dumped from a template. Anything we access along the way stays confidential.
Capabilities
-
SIM
Adversary Simulation
We simulate how real threat actors operate, working through the Tactics, Techniques, and Procedures (TTPs) seen in genuine intrusions. It shows how your detection and response hold up against realistic activity, and where an attack would be caught, missed, or slowed down.
-
BREACH
Assumed Breach Testing
We start from a position an adversary might already hold inside the network, such as a compromised workstation or a set of valid credentials. From there we measure how far that access reaches, what it exposes, and how quickly your team notices.
-
OSINT
Open-Source Intelligence Gathering
We gather what an adversary could learn about your organization from public sources, including staff, technologies, infrastructure, and exposed data. It gives you a clear picture of your external footprint and the information that makes targeting easier.
-
WEB
Web Application Penetration Testing
We test web applications and the APIs behind them for weaknesses in authentication, access control, injection, and business logic. Testing covers both the common entry points and the flaws in how the application is meant to work.
-
AD
Active Directory Penetration Testing
We look at how an adversary could move from a single low-privileged account toward control of the domain. The focus is the chain of misconfigurations, weak permissions, and credential exposure that turns a small foothold into full compromise.
-
NET
Network Penetration Testing
We test the edges of your internal and external networks for the exposed services that hand an adversary a foothold. From there we assess how far that foothold reaches and how easily it allows movement between systems.
-
MOBILE
Mobile Application Penetration Testing
We review iOS and Android applications across the client, on-device storage, and the APIs they depend on. Testing looks at how each app protects data at rest and in transit, and how it behaves on a device outside your control.
-
WIRELESS
Wireless Network Penetration Testing
We test the wireless edge for rogue access points, weak authentication, and gaps in segmentation between wireless and internal networks. It covers the point where physical proximity starts to translate into network access.
-
CUSTOM
Custom Security Solutions
For work that doesn't fit a standard scope, we build engagements around your environment, whether that means bespoke tooling, focused research, or testing shaped to a specific product, technology, or threat.
