Detect, exploit, and fix every AI attack vector — before your adversaries do.

SREPRIMER delivers AI-native security testing and real-time threat detection across the OWASP LLM Top 10 — from prompt injection to supply chain compromise — with working demos for every threat class.

10OWASP LLM vectors covered

0Legacy tools detect LLM attacks

Your existing security stack has a blind spot the size of your entire AI surface.

Every SIEM, EDR, and WAF in your organisation was built before LLMs existed. They cannot detect, classify, or respond to the attack patterns that are unique to AI systems.

LLM01

Prompt injection is invisible to legacy tools

Injection payloads look like normal user text. They pass every signature-based filter and arrive at your LLM undetected — where they extract credentials, override system instructions, or exfiltrate data.

16,000+

Malicious packages removed from PyPI in 2024

AI developers install dozens of ML packages per project. Any one could be a typosquatted supply chain attack executing credential theft during pip install — before your app even runs.

72h

Average time to detect an AI-specific breach

Without AI-native monitoring, backdoored models, poisoned pipelines, and compromised endpoints run undetected for days. By the time logs surface an anomaly, the damage is done.

Red team the AI. Then harden it. Then monitor it.

SREPRIMER follows a three-phase engagement model — assess the attack surface, implement defences, then deploy continuous monitoring. Every phase maps to OWASP LLM Top 10 and MITRE ATLAS.

We don't produce reports describing theoretical risks. We demonstrate the attack working on your system — then show you exactly what stops it.

Audit-ready reporting

Five threat classes. Five working demos. One integrated programme.

Each service maps to a specific OWASP LLM Top 10 category. Every engagement includes a live attack demonstration — not a slide deck. Expand each to see what's included.

01

Prompt Injection Testing & Hardening

Attack and defence — live, side-by-side on a real LLM instance

OWASP LLM01

The #1 LLM attack vector — tested live on your system

Prompt injection is the most exploited LLM vulnerability class. Attackers craft inputs that override system instructions, extract embedded secrets, or jailbreak your model entirely. We demonstrate five distinct attack payloads, then implement four defence layers that block every one.

  • Completion injection attacks
  • Indirect injection via tool outputs

Live attack timeline
1
OWASP LLM01
System prompt extraction

Attacker uses role-play framing to leak internal instructions and embedded secrets.

2
OWASP LLM01
Credential exfiltration

Social engineering chain prompts model to recall and repeat API keys embedded in context.

3
OWASP LLM01
Jailbreak — DAN pattern

Persona override bypasses safety constraints. Model operates without restrictions.

SREPRIMER DEFENCE
All payloads blocked

4-layer defence stack intercepts at input, detects pattern, hardens prompt, and redacts output.

02

Data Poisoning Detection & Model Integrity

Backdoor triggers, label flipping, and confidence score anomaly analysis

OWASP LLM03

Backdoors that survive your accuracy testing

A poisoned model achieves identical accuracy on standard benchmarks while containing a backdoor that activates on a trigger keyword — silently flipping classifications or behaviours in production. Standard ML validation never finds it. SREPRIMER's targeted sweep does.

LLM API Security Assessment & Hardening

Unauthenticated endpoints, excessive tool permissions, and rate limit bypass

OWASP LLM06

Five attacks via one unprotected endpoint

An LLM API with no authentication, no rate limiting, and unrestricted tool access is a single point of catastrophic failure. In this engagement, we execute five distinct attacks against your endpoint — exfiltrating PII, triggering mass phishing, and approving transactions — then implement five defence layers that block every one.

⚠ Attacks executed

  • Transaction auto-approval bypass
  • Database credential exfiltration

AI Supply Chain Security Audit

Typosquatting detection, install hook analysis, and dependency integrity verification

OWASP LLM05

The attack that happens before your app runs

Malicious PyPI packages masquerade as legitimate ML libraries. Their install hooks execute credential theft and backdoor injection during pip install — before your application runs, before your scanner activates. The developer sees only "Successfully installed." SREPRIMER catches this before the install executes.

OWASPLLM05 — Supply Chain Vulnerabilities
MITREAML.T0010 — ML Supply Chain Compromise
Duration1 day audit + CI/CD integration sprint
DeliverableDependency audit report + scanner integration + lockfile policy
⚠ What we find

  • Install hooks in setup.py / pyproject
  • Checksum mismatches vs PyPI records
  • Unverified authors and low-signal packages
  • Injected backdoors in site-packages

AI Security Monitoring & Observability

Real-time alert feed — all attack types unified in one executive dashboard

OWASP LLM08

The gap most CISOs don't know they have

Without AI-specific monitoring you have no audit trail, no incident evidence, and no compliance story. SREPRIMER deploys a unified security operations view — every LLM threat class surfaces as a real-time alert mapped to OWASP and MITRE ATLAS, with one-click evidence export per event.
