Anticipate. Detect. Respond.

With a 360° view of your security, we support you at every stage: before, during and after an attack.

During an attack

Detect

Our goal is to spot a cyberattack as early as possible, before it does damage. To do that, we help you get the most out of your cyber defence tools (SIEM, EDR, XDR, identity, cloud and email protection): assessment, integration and configuration, then a detection strategy shaped by the threats you face and what matters to your business.

    Reduced risk

  • 02

Audit and assessment

Shrink your attack surface

We assess your information system from an attacker's point of view: which paths lead to your admin accounts, which vulnerabilities can actually be exploited, which misconfigurations let them in. Each finding is then ranked by its impact on your business.

  • Active Directory: attack paths, privileged accounts, delegations and Kerberos
  • Network: segmentation and internet-facing services
  • Systems: server and workstation hardening against CIS Benchmarks
  • Vulnerabilities: authenticated scans, internal and external
  • Compliance: gaps against ISO 27001

OutcomeA detailed report, findings ranked by severity and a prioritised 90-day remediation plan that accounts for your business constraints.

SOC tools

Get the full potential out of your SOC tools

Most organisations use only part of their security tooling: logs collected with no priority, rules left on default, repetitive tasks handled by hand and alerts nobody trusts any more. We help you get the full value out of what you already own, so every alert counts and your teams can focus on what matters.

  • Ingestion pipeline: log collection, normalisation and enrichment, from source to analysis
  • Log prioritisation: the sources that matter against your threats collected first, for better coverage at a controlled cost
  • Coverage and tuning: your whole estate covered, hardened protection policies, risky exclusions removed
  • Identity protection: privileged account monitoring, detection of authentication abuse and suspicious access
  • Automation: alert enrichment and first response actions automated, saving time on every incident
  • Detection strategy: use cases built around the threats targeting your sector and what matters to your business

OutcomeTooling that covers your whole information system, alerts you can trust and automated processes your teams own.

Detection engineering

Detection built around your business

Generic rule packs flood analysts with alerts that have nothing to do with your risks. We start from your business: the assets that matter, the threats that target your industry and the logs you actually collect. Then we build the detections that give you the most protection for the effort.

  1. Prioritise your logsRank log sources by detection value and cost, and onboard first the ones that see the most attacker activity.
  2. Map your ATT&CK coverageMeasure which attacker techniques you can already see, and where your blind spots are.
  3. Focus on your risksSelect the use cases that matter for your industry, your critical assets and the threat actors targeting your sector.
  4. Build and validateWrite each rule as code and prove it fires against an emulated attack.
  5. Tune continuouslyReview false positives every month and adapt detections as your business and the threats change.

OutcomeA detection roadmap tied to your risks, an ATT&CK coverage map and a versioned rule library.

Threat hunting

Hunt the adversaries your alerts missed

Skilled attackers know how to stay under detection thresholds. Our hunters start from how they would operate in your environment and search the raw telemetry for the traces they leave.

  • Hypotheses built from the threats targeting your sector and your own exposure
  • Hunts across EDR, SIEM and cloud telemetry
  • Every finding confirmed, scoped and escalated to incident response when needed
  • Each hunt ends with a new detection rule

OutcomeHunt findings, plus new detections for what we uncover.

Incident response

When an incident hits, we take the lead

We follow the NIST SP 800-61 lifecycle and document every decision, so your board, your insurer and your regulator can see what was done and why.

  • Ransomware, intrusions, business email compromise and insider threats
  • Containment using your EDR, firewall and identity controls
  • Disk, memory and log forensics
  • A report written for executives, insurers and regulators

OutcomeA contained incident and a full investigation report.

The four phasesNIST SP 800-61
  1. 1

    Prepare

    Agree the response plan, contacts, log retention and access before an incident.

  2. 2

    Detect and analyse

    Confirm the compromise, identify patient zero and scope every affected system and account.

  3. 3

    Contain, eradicate, recover

    Isolate hosts, revoke access, remove persistence and restore services safely.

  4. 4

    Lessons learned

    Root cause, a full timeline and new detections that close the path the attacker used.

Cloud security

Secure Microsoft 365, Azure and AWS

Most cloud breaches start with a stolen identity or a misconfiguration. We audit both, make sure you keep the logs an investigation needs, and respond when an account or a tenant is compromised.

Microsoft cloud

Microsoft 365, Entra ID, Azure, Defender for Cloud

Audit

  • Conditional Access, MFA coverage and legacy authentication
  • Privileged roles, PIM and break-glass accounts
  • Exchange Online mail flow rules and external forwarding
  • Azure subscriptions against the Defender for Cloud secure score

Incident response

  • Session and token revocation for compromised accounts
  • Unified Audit Log and sign-in log investigation
  • Removal of malicious OAuth apps and inbox rules

AWS

IAM, CloudTrail, GuardDuty, Security Hub

Audit

  • IAM users, roles, access keys and least privilege
  • CloudTrail, Config and VPC flow log coverage across accounts
  • Public S3 buckets, security groups and exposed services
  • Security Hub findings against the CIS AWS Foundations Benchmark

Incident response

  • Leaked access key containment and credential rotation
  • CloudTrail timeline of the attacker's API calls
  • Cleanup of rogue IAM entities and crypto-mining resources
