Expert-led security for AI and LLM systems

Large language models introduce leakage, prompt injection, unsafe agent behavior, and access paths traditional controls miss. SubRosa runs targeted assessments focused on real failure modes and enterprise integrations.

  • Sensitive training data and contextual information leakage
  • Prompt injection, jailbreaks, and system prompt exposure
  • Agent, tool, and plugin misuse or escalation
  • Integration and API access across enterprise systems

Our Process

A simpler way to approach cybersecurity

Clarity at every stage, so teams know what to fix, why it matters, and what to do next.

Discovery

Automated coverage and hands-on probing keep networks, applications, cloud, and AI workflows visible without drowning teams in noise.

  • Confirm scope, dependencies, and data flows across infrastructure, cloud services, and AI integrations.
  • Map externally reachable and internal attack surface, then validate what’s exploitable with practitioner-led testing.
  • Document the paths that matter, so engineering and leadership share the same picture of risk.

Analysis

Practitioners synthesize impact, chain attack paths, and translate findings into prioritised guidance leadership can act on.

  • Prioritize findings by impact and likelihood, not by volume or generic severity labels.
  • Chain weaknesses into realistic scenarios so teams understand how risk compounds.
  • Translate technical detail into clear decisions for engineering owners and executive stakeholders.

Remediation

Clear steps, proof-of-fix validation, and collaboration with your teams ensure the loop is closed and fixes stick.

  • Turn findings into a sequenced plan with owners, dependencies, and “what good looks like.”
  • Retest and validate fixes so teams can close items with confidence.
  • Provide concise updates that keep engineering and leadership aligned through closure.

Security services built for real-world risk

Outcome-led engagements guided by practitioners who filter the noise, focus on impact, and stay through response.

Continuous monitoring, human-led triage, and executive-ready communication keep threats contained while teams concentrate on delivery.

  • Human-led alert triage that filters noise and escalates what matters.
  • Clear incident communication for security leaders and internal stakeholders.
  • Ongoing tuning aligned to your environment, priorities, and risk tolerance.
Explore Managed Security

Network, application, cloud, and AI testing informed by adversary tradecraft exposes the attack paths automation misses and maps remediation to impact.

  • Penetration testing across network, web apps, cloud, and modern AI integrations.
  • Attack-path narratives that show how findings chain into real outcomes.
  • Actionable remediation guidance with proof-of-fix validation as needed.
Explore Offensive Security

Pragmatic program alignment, tabletop exercises, and reporting that translates technical risk into board-level guidance, so leadership can make clear decisions.

  • Executive-ready reporting that connects technical risk to business decisions.
  • Tabletop exercises and readiness reviews grounded in real incident scenarios.
  • Program guidance that prioritizes impact without unnecessary complexity.
