Compromise Assessment Services

Know if threat actors are already inside your environment.

Overview

Hidden compromises cause long-term business impact. Threat actors often persist inside environments without triggering alerts, leaving organisations unsure whether their systems are safe.

Reliance Cyber’s Compromise Assessment service provides a structured, intelligence‑led investigation that identifies active or historic compromises, uncovers exposure paths and gives you clear evidence of what has happened across your estate.

The assessment draws on DFIR tooling, threat intelligence and expert analysis to identify risk, confirm or rule out compromise and create a clean baseline for future improvement. If an active threat is identified, we switch immediately into emergency response mode as defined in our Professional Services Catalogue.

Cyber security outcomes we deliver

Confirmation of compromise

Identify whether active, historic or dormant threats exist using IoCs, TTPs and forensic analysis across your environment.

Understanding of cyber threat activity

Get a clear timeline of threat actor actions, entry points and any attempted lateral movement.

Identified root causes

Understand misconfigurations, vulnerabilities or process gaps that enabled exposure.

Immediate risk reduction

Receive prioritised remediation actions mapped to business risk so you can fix the most important issues first.

Clean baseline for future security work

Establish a known-good state to support ongoing improvements and reduce uncertainty.

Rapid escalation if required

If a live compromise is found, the engagement is escalated instantly to incident response under agreed emergency processes.

Analysis of endpoints, servers, networks and cloud systems provides coverage across your estate, uncovering activity your tools may not surface.

Every finding is tied to forensic data, making it suitable for boards, insurers and auditors.

Targeted recommendations


You receive a clear, prioritised action plan for reducing risk, removing attacker footholds and hardening your environment.

Threat profiles are aligned to realistic attacker behaviours seen across the sector, increasing the relevance and accuracy of findings.

Once complete, you gain clarity and confidence that strengthens incident readiness and informs strategic investment.

If an active threat is discovered, our team transitions to emergency response without losing time, ensuring continuity of handling.

How it works

Our Compromise Assessment follows a structured and repeatable process. We gather the right data, analyse it against credible threats and provide clear outputs you can act upon.

step1

Deploy DFIR tooling

We collect endpoint, network and cloud data using dedicated forensic tooling to build an accurate picture of your environment.

step2

Threat intelligence profiling

Analysis is guided by realistic threats to your organisation, using external and sector-specific intelligence to focus the investigation.

step3

Compromise identification

We identify active or historic compromises using IoCs, TTPs and forensic techniques across logs, hosts and cloud telemetry.

step4

Risk and exposure analysis

We highlight vulnerabilities, misconfigurations and lateral movement risks that contributed to or could contribute to compromise.

step5

Report & recommend

You receive a detailed report with evidence, risk scoring and prioritised remediation recommendations, as well as a long-term threat defence plan.

Compromise Assessment FAQs

Q: What is a Compromise Assessment?

A: 

An investigation that identifies active or historic compromises across your environment using DFIR tooling, threat intelligence and forensic methodologies.

Q: What does a Compromise Assessment include?

A: 

Data collection, IoC and TTP analysis, detection of malicious activity, exposure mapping, and a full findings and remediation report .

Q: What happens if a breach is found?

A: 

If a live threat is identified, we transition immediately into emergency response mode as defined in the Professional Services Catalogue.

Q: How long does a compromise assessment take?

A: 

Time varies by estate size, but the process is structured, measurable and delivered with clear outputs.

Q: When should an organisation request one?

A: 

When suspicious activity is detected, ahead of M&A, after a supplier breach, or when organisations want assurance that hidden threats are not present.

Q: What are indicators of compromise in cyber security

A: 

Indicators of compromise are warning signs that a system may be breached, such as unusual network traffic, unknown processes, or suspicious login activity.

Q: What is the difference between a compromise assessment and incident response?

A: 

A compromise assessment determines if a breach exists; incident response acts to contain and eliminate a confirmed breach.
