An AI security engineerthat works like a human.

It joins your meetings, talks through findings, and tests your whole stack — web, mobile, cloud, APIs, internal networks, and infrastructure — attacking like a real adversary and proving every finding with a working exploit.

01 / MEET NEBULA

Built like a hacker. Thinks like one too.

Two halves of one operator: a chat agent you brief like a teammate, and an autonomous swarm that hunts and exploits. Built from real offensive tradecraft, it reasons about your systems instead of pattern-matching, and remembers every weakness it finds.

Real tradecraft, encoded into AI.

Every payload, chain, and evasion in Nebula is grounded in real offensive tradecraft — not a research demo. Battle-tested techniques, encoded into AI and proven with working exploits.

+ spawns specialists on demand

One target in. A whole team out.

Nebula deploys a coordinated swarm of specialist agents across 30+ roles, spawning more on demand for each finding. A Team Lead orchestrates the operation and chains findings into multi-step attack paths and complete kill chains that no single tool could discover.

Reasoning Engine

Chain-of-Thought

Multi-step attack planning

Situational Awareness

Real-time defence adaptation

Surface Mapping

Hidden endpoint discovery

Autonomous Pivot

Auto-escalation on findings

It reasons. It doesn't pattern-match.

Chain-of-thought reasoning to plan multi-step attacks, adapt when defences push back, and understand the full business context of what it's testing. Not pattern matching, but genuine offensive reasoning.

9-Layer Memory

Short-Term

Active engagement context

Long-Term

Cross-scan intelligence

Episodic

Past engagement patterns

Semantic

Global attack knowledge

It never forgets a weakness.

Nebula remembers which payloads bypassed your WAF, which endpoints were patched, and which attack chains still work. A 9-layer memory system that mirrors how human experts retain knowledge, so every scan feeds back into a growing intelligence layer.

02 / HOW IT WORKS

No rules.
Just reasoning.

Six phases, start to finish, with nothing hardcoded. Nebula decides which surface to hit, which exploit to try, and when to pivot, adapting live as your environment changes. You watch it work and approve anything sensitive.

PHASE 1 / 6

Brief It Like a Teammate. In Any Language.

Message Nebula on Slack or email, or have it join your Teams/Zoom call — it talks, listens, asks clarifying questions, and builds a complete profile of your target.

03 / WHAT NEBULA FINDS

Your scanner says you're fine. Nebula disagrees.

Proof-carrying exploit chains, not CVE noise: IDOR, SSRF-to-cloud-takeover, JWT confusion, race conditions, business-logic flaws. Every finding ships with a working reproduction.

Payment Bypass via Race Condition

CRITICAL

RACE CONDITION → £0 CHECKOUT → UNLIMITED FREE ORDERS.

Nebula analysed your checkout flow and found a time-of-check/time-of-use flaw. By sending 50 requests at once during the payment window, it placed orders with a £0 balance. A scanner never finds this, because it takes understanding your business logic.

04 / EXPERT SERVICES

Continuous coverage. Expert engagements.

Run Nebula continuously across your whole estate, or bring in a scoped, expert-led engagement when you need board- and auditor-ready sign-off. Reports map to PCI-DSS, SOC 2, ISO 27001, and NIST.

Web & Mobile App Testing

Black-box and authenticated testing of web apps, APIs, and mobile, mapped to OWASP and PTES. We chain real exploits to business impact, not CVSS noise.

Infrastructure & Network Testing

External and internal infrastructure, cloud, Kubernetes, and Active Directory. We trace the path from first foothold to domain admin.

Board & Executive Review

Security-posture reviews, secure-architecture and threat-model assessments, and board-ready reporting your leadership and auditors act on.

Red Team & Continuous Assurance

Full-scope adversary emulation, plus Nebula testing continuously between engagements so a new exposure becomes a validated finding in hours.
