OFFENSIVE SECURITY · PENETRATION TESTING
We attack first, so you're
ready when it's real
We work as an extension of your team to surface the viable attack paths an adversary could take, so you can close them and face the real thing with confidence.
Built to attack
Fortreum Override is Fortreum's offensive security practice. We become the adversary – chaining exploits to demonstrate the real world impact of a successful attack. We tell you what an attacker would actually do, then work alongside your team to close the paths we find.
On your side
WHY OVERRIDE
Get there first. prove it. close it.
Most tests hand you a list of what's wrong. We hand you proof of what's exploitable, and a clear path to close it.
We move first
We run the adversary's scenario and map the routes they'd take, so you can close the highest-risk paths first.
Proof, not theory
Every finding comes with a working exploit, the evidence, and the steps to reproduce it.
Navigate and test the system
We work to understand your environment well enough to author its behavior. That depth is what lets us help you close paths, not just flag them.
Mapped to what matters
Findings map to MITRE ATT&CK and ATLAS, OWASP, and the standards regulators recognize, so they translate straight to compliance, governance, and the board.
THE MATURITY MODEL
From a first assessment to a full red team
Twelve services across three maturity tiers, plus flagship AI & LLM security and COAST continuous testing available at every stage.
// TIER 01
Essential / Foundation
Establish your baseline. Vulnerability assessment, external network testing, social engineering, and executive cyber hygiene.
Explore Essential // TIER 02Advanced / Validation
Validate controls under real attack conditions. Compliance, internal and wireless, application, and cloud testing, plus code, product, and IoT review.
Explore Advanced // TIER 03Expert / Simulation
Stress test the whole program. Red and purple team operations, AI and LLM testing, AIUC-1 validation, and threat intel-led engagements.

// Flagship
Explore AI & LLM Security
AI & LLM Security
AI Offensive Security & Penetration Testing (AOSPT) plus AIUC-1 certification. We test the model, the agent, and the trust boundary — mapped to the OWASP LLM Top 10 and MITRE ATLAS.
// Continuous overlay
Explore COAST
COAST — available at every tier
Continuous Offensive Assessment and Security Testing. Ongoing validation across every stage of your program, not a one-time engagement.

HOW WE PARTNER
A partner before, during, and after the engagement
The offense is pointed at the adversary, never at you. We work as an extension of your team, and we're measured by whether you come out more secure.
Transparent from day one
A dedicated Slack or Teams channel, daily standups, and same-day alerts on critical findings. No black box, no surprises at the readout.
Collaborative by design
On purple team engagements our operators work alongside your blue team in real time, so your people build detection and response skills that stay after we leave.
We meet you where you are
Engagement depth matches your program's maturity, from a first assessment to a continuous red team. We help you choose the right starting point, not the biggest one.
We don't disappear at the report
Remediation retesting, a debrief workshop, and a path into continuous testing. We stay with you to close what we find, not just document it.
COMMON QUESTIONS
Straight answers before you scope
Does passing a compliance penetration test mean you're secure?
No. A compliance penetration test confirms you meet a standard, not that you're secure. Fortreum Override runs real exploitation and chained attack paths, not scanner output, and shows you what an adversary could actually do and how far they'd get. Every finding still maps to the frameworks regulators recognize, so it works for the audit too.
Does FedRAMP require a red team exercise?
Yes. Under NIST SP 800-53 Rev. 5, control CA-8(2), red team exercises are an organizational control for FedRAMP Moderate and High systems, performed at least annually. The exercise is not required to be run by a 3PAO — internal teams and third-party providers are both allowed — and final FedRAMP guidance is still in draft. Fortreum is a FedRAMP and GovRAMP 3PAO and runs both the FedRAMP penetration test and the red team exercise.
How long does a penetration testing engagement take?
Most Fortreum Override engagements run 2 to 6 weeks, scoped to the size, complexity, and risk of your environment. Each one moves through six phases: scoping and rules of engagement, reconnaissance, exploitation, analysis, reporting, and validation. Throughout, you get a dedicated Slack or Teams channel, daily standups, and alerts on critical findings the same day.
Do you offer penetration testing for AI, LLM, and agent systems?
Yes. Fortreum Override tests AI, LLM, and agent systems the way an adversary would, targeting model behavior, trust boundary violations, agent and tool abuse, and data leakage that traditional penetration testing misses. Findings map to the OWASP Top 10 for LLM Applications and MITRE ATLAS. We also offer AIUC-1 validation, an AI agent security certification backed by a consortium of 75+ Fortune 500 CISOs.
What certifications do your penetration testers hold?
Fortreum Override's testers hold industry certifications including OSCP, OSCE, GXPN, GPEN, CRTO, PNPT, and OSIP. Fortreum is also a FedRAMP and GovRAMP 3PAO, PCI QSA, CMMC C3PAO, and a SOC, ISO, and HITRUST assessor, so our operators know what auditors and regulators expect.
Where should we start if we're new to offensive security testing?
Start wherever your program is today. Fortreum Override is built as a maturity model with three tiers: Essential, Advanced, and Expert, so a first vulnerability assessment and an enterprise red team program are both valid starting points. COAST continuous testing is available at every stage as your program matures.
What deliverables do you get after a penetration test?
Every Fortreum Override engagement ends with proof of concept evidence for each finding: prompts, logs, screenshots, and reproduction steps. You also get an executive summary that translates risk into business impact for leadership and the board, and prioritized remediation guidance your engineers can act on. Remediation retesting and a debrief are included.
