When a cyber incident strikes, the difference between swift resolution and prolonged organisational crisis is the right response — deployed immediately, led by certified experts who have done this thousands of times before.
Major cyber incidents place intense stress and scrutiny on even the most experienced internal teams. Questions come from every direction — the board, legal counsel, regulators, insurers, the press. The organisations that navigate this best share one characteristic: they prepared.
A pre-contracted incident response retainer transforms your position entirely. Your response team already knows your environment, your key contacts, your critical systems and your regulatory obligations. When an incident is declared, response begins from a place of knowledge — not from zero.
"The key to incident response is not reaction — it is anticipation. The element of surprise is the attacker's greatest advantage. A retainer removes it."
Musketeers Security offers three straightforward retainer tiers — designed to give every organisation, regardless of size or sector, guaranteed access to certified, experienced responders the moment they are needed.
Our retainer plans are designed to be understood and signed quickly. Each tier provides a different level of embedded readiness — from guaranteed rapid access to a fully onboarded, deeply embedded response relationship.
Pick the tier that matches your priorities: fast response with no commitment, pre-purchased hours with proactive rollover services, or in-depth onboarding and the fastest SLAs for complex environments.

Speak to our teamOur methodology has been honed across thousands of incidents globally. Every engagement follows the same five-phase process — adapted in real time as the picture develops, with a consistent focus on minimising business impact and preserving the evidence chain your regulators and insurers expect.
Rapid assessment of scope, severity and active threat presence. Contain before investigating.
Isolate systems, revoke credentials, cut adversary access — without destroying evidence.
Establish the full attack timeline — initial access, lateral movement, data accessed or exfiltrated.
Remove all attacker persistence. Restore systems securely with hardened configurations.
Detailed forensic report for regulators, insurers and board with prioritised recommendations.
Our responders have handled every form of cyber attack across every major sector. Whatever the technique, our process is the same — fast, forensically sound and focused on your outcome.
Rapid containment and recovery path assessment across every major ransomware family. Negotiation support where required.
Full forensic scope on M365 and Google Workspace with detailed reports for insurers and legal counsel.
Establish precisely what data was accessed, by whom and when — the evidential foundation for ICO notification and insurer claims.
Investigate confirmed or suspected unauthorised access — external attacker or insider — mapping the full scope of compromise.
Cloud-native forensics across Azure, AWS and GCP — identity compromise, control plane abuse and cloud storage exfiltration.
Every engagement produces an auditable evidence chain aligned to what the ICO, NIS2, DORA, your insurers and legal counsel require.
