IR Retainer vs. Break-Fix Incident Response: Which Makes Sense?

When a ransomware attack hits, you have two options: call a firm you have a retainer with, or start cold-calling IR firms and negotiating contracts while your network burns.

The difference in outcomes is significant. Here is a clear comparison.

What a Break-Fix Engagement Looks Like

You detect an incident. You call three IR firms. Each requires:

Signing an MSA (Master Service Agreement) — 4–8 hours
Negotiating scope and hourly rates — 2–6 hours
Onboarding the IR team to your environment — 4–24 hours (no documentation)
Deploying forensic tooling — 2–8 hours

Total elapsed time before real investigation starts: 12–48 hours

Meanwhile, the attacker has full access to your environment. In a ransomware scenario, they may have already deployed encryption by the time your IR team starts working.

Cost: Break-fix IR engagements are billed at premium emergency rates — typically $350–$600/hour. A mid-sized incident runs $50K–$300K.

What an IR Retainer Looks Like

You detect an incident. You call your retainer hotline.

Your NDA and MSA are already signed
Rates are pre-negotiated (typically 20–30% below break-fix emergency rates)
The IR team already has environmental documentation (network maps, asset inventory, contacts)
Forensic tooling may already be deployed (some retainers include pre-positioned agents)

Total elapsed time before investigation starts: 30 minutes to 2 hours

That difference — 12–48 hours vs. 2 hours — is often the difference between encrypting 10 systems vs. 500.

Retainer Cost vs. Break-Fix Cost

	Break-Fix	Retainer
Rate	Emergency premium ($350–$600/hr)	Pre-negotiated ($200–$400/hr)
Mobilization time	12–48 hours	1–2 hours
Environmental familiarity	Zero	Pre-onboarded
Minimum fees	Often $25K–$50K minimum	Annual retainer fee
Total typical cost (mid-size incident)	$100K–$500K	$80K–$300K + retainer

For most organizations with >$500M revenue or >500 employees, a retainer is the economically rational choice — even if it is never invoked.

What Security Arsenal's Retainer Includes

Security Arsenal's IR Retainer includes:

2-hour SLA for active incidents
Pre-negotiated rates locked in at time of signing
Annual readiness review and tabletop exercise
Pre-positioned environment documentation
Priority access to forensics and malware analysts
Integration with AlertMonitor for pre-positioned telemetry

Who Should Get a Retainer?

Strong case for a retainer if you:

Have >200 employees
Process payment card data, PHI, or PII at scale
Have compliance requirements (HIPAA, PCI, SOC 2, CMMC)
Are in a high-target sector (healthcare, financial services, manufacturing, government contractors)
Have experienced a near-miss or breach in the last 3 years

Break-fix may be acceptable if:

You are a very small organization (<50 employees, limited data)
You have cyber insurance covering emergency IR costs
You have a mature internal IR capability
