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 an offensive security company providing penetration testing, adversary simulation, and offensive research. 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 ten years of penetration testing experience across banking, retail, commerce, oil and gas, and telecommunications, running engagements at every organizational scale, 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 a report you can act on: each finding prioritized by the risk it presents in your environment, 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 written by the operators who ran the engagement and delivered directly, not generated 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.
-
CLOUD
Cloud Penetration Testing
We test AWS, GCP, and Azure environments, from what is exposed to the internet to what an adversary can reach with a single low-privileged identity. Testing covers identity and access, configuration, exposed storage and services, and the paths that lead from one compromised identity to the rest of the estate.
-
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 does not 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.
How we engage
It starts with a scoping call, free and without obligation. We then issue a fixed-fee proposal or a statement of work, both parties sign the written authorization and rules of engagement, and testing runs within the agreed window, with critical findings reported as they are confirmed. We deliver the report, walk your team through it, and retest once you have remediated.
What you receive
A technical report covering every validated finding with its severity, evidence, reproduction steps, and remediation guidance; an executive summary for leadership; a live readout; and one retest of remediated findings within the agreed window. A letter of attestation for your customers or auditors is available on request.
