Incident Response Planning for MSPs & IT Consultancies
An incident response plan for an MSP or IT consultancy has to answer a question a single-site business never faces: what happens when one compromised console reaches every client at once. The trigger is usually a supply-chain scare in the trade press, a client's PHIPA or HIPAA notification clock the firm didn't know it was on, or the plain absence of any tested plan at all. We build the plan around the firm's actual blast radius and rehearse it before an incident forces the question.

What you're protecting
What the plan has to account for that a single-tenant business plan doesn't
A normal incident response plan assumes one victim. An MSP's plan has to assume dozens, notified on different timelines, under different regimes.
Per-client notification triggers
A pre-built map of which client contracts, and which regulatory regimes, set the notification clock once an incident is confirmed, so the response doesn't start with research.
RMM and PSA containment steps
Documented steps to isolate or disable the RMM console, revoke GDAP roles and lock down remote-access tools quickly enough to stop lateral movement into client tenants.
Break-glass account procedures
A defined process for using break-glass credentials during containment, logged and reviewed afterward so the emergency access itself doesn't become the next incident.
Client communication templates by regime
Draft notifications suited to a PHIPA custodian, a HIPAA covered entity and a general commercial client, so the firm isn't drafting three different messages from scratch under pressure.
Insurer and law enforcement contacts
Current contact details for the cyber-insurance carrier's breach coach, outside counsel and the appropriate law enforcement contact, confirmed before an incident, not looked up during one.
Regulatory map
Why the plan has to be built around multiple notification clocks
An incident touching several clients doesn't get one deadline. It gets as many deadlines as there are regimes represented in the client book.
PHIPA's first-reasonable-opportunity standard
Ontario Regulation 329/04 requires a health information network provider to notify affected custodians at the first reasonable opportunity, a standard the firm has to be ready to meet the moment an incident is confirmed, not after internal debate.
HIPAA's contractual breach window
A Business Associate Agreement sets the clock for notifying a US covered entity, and that window is usually shorter than a firm's default incident-review timeline unless the plan accounts for it explicitly.
PIPEDA's transferring-organization accountability
OPC guidance keeps the client accountable for its own s.10.1 breach report even when the incident originated at the firm, which is exactly why the response plan has to get the client accurate information fast.
AA22-131A's incident-notification expectation
The joint CISA/CCCS advisory expects MSPs to have a tested incident response capability specifically because state-sponsored actors target this sector to reach its customers, not just the firm itself.
What goes wrong
The incidents that make one console a multi-client emergency
These aren't hypothetical scenarios. They are the specific events this plan is built to have already answered.
Kaseya VSA, July 2021
A single zero-day in Kaseya's VSA platform let REvil push ransomware through roughly sixty MSPs to as many as fifteen hundred downstream businesses simultaneously, the incident that defines what a plan here has to be ready for.
ScreenConnect's mass-exploited bypass
CVE-2024-1709 was weaponized within days of disclosure, and firms without a rehearsed containment step for remote-access tools lost the narrow window that separated one compromised session from many.
Credential-based access without MFA
The 2024 Snowflake-linked campaign shows how stolen credentials against tools without multi-factor authentication turn into mass compromise, a root cause the plan's containment steps have to address directly on RMM and PSA logins.
Departed staff retaining admin access
An offboarding failure that leaves a former technician's credentials active is a slower-burning version of the same risk, and the plan needs a step that checks for it as part of every incident, not a hiring-and-firing policy filed separately.
Our incident response for msps & it consultancies
What our incident response plan covers for an MSP
A living document built for the specific way an incident here can spread, not a generic template with the company name swapped in.
Custom incident playbooks
Playbooks built around the firm's actual RMM, PSA, remote-access and backup stack, not generic categories that don't map to what the technicians actually use.
Compliance-ready notification sequencing
A sequence that accounts for PHIPA, HIPAA, PIPEDA and provincial timelines simultaneously, ordered by which clock is shortest rather than treated as one uniform step.
Employee and vendor roles
Clear responsibilities for technicians, account managers and leadership during an incident, plus defined expectations for RMM, backup and distributor vendors who may need to be looped in.
Tabletop exercises
A rehearsal built around a realistic scenario, an RMM compromise reaching several clients at once, so the plan is tested against pressure before it's tested by an actual attacker.
Ongoing updates
Revisions as the firm adds RMM tools, onboards new regulated clients, or as government guidance and client contract terms evolve.
How the engagement runs
How we build and maintain the plan
Structured so the firm ends up with something technicians would actually open during an incident, not a document written once and filed.
Step 1
Map the blast radius
We inventory which systems reach which clients, and which client contracts set which notification obligations, before drafting a single procedure.
Step 2
Draft the playbooks
Containment, eradication and notification steps are written around the firm's actual tools and the regimes its client book represents.
Step 3
Run a tabletop exercise
The plan is tested against a realistic multi-client scenario, surfacing gaps in ownership, contact information or sequencing before a real incident does.
Step 4
Finalize and distribute
The plan is put where technicians and leadership can find it during an outage, with contact information and playbooks kept current.
Step 5
Review on a schedule
The plan is revisited as tools, clients and threats change, so it doesn't quietly go stale between the rare moments it's actually needed.
What it costs
What determines incident response plan cost for an MSP
Cost tracks the complexity of the stack and client book being planned for: how many RMM and PSA tools are in use, how many regulatory regimes the client base represents, and whether a tabletop exercise is included.
The plan is typically built as a fixed-scope project, and is often maintained afterward inside a Virtual Privacy Office retainer so it stays current as clients and tools change rather than aging on a shelf. We quote after reviewing the firm's stack and client mix.
MSPs & IT Consultancies: Incident response questions, answered
It starts from a different assumption than a normal business continuity plan: containment steps for the RMM and remote-access tools come first, because stopping lateral movement into client tenants is often more urgent than the firm's own recovery. Notification then follows a sequence built around whichever client's regulatory clock is shortest, rather than one uniform timeline for everyone.
In practice these run in parallel rather than in strict sequence: the cyber-insurance carrier's breach coach is typically engaged immediately because they often coordinate outside counsel and forensics, while affected clients need enough information to start their own obligations, including any regulator notice they owe directly. A pre-built contact list and message templates are what make that parallel response possible instead of chaotic.
Ontario Regulation 329/04 requires a health information network provider to notify the affected custodian at the first reasonable opportunity, a standard of speed rather than a fixed number of days, and custodians expect notice quickly enough to meet their own obligations to patients and the IPC. Building that notification into the plan in advance is what keeps "first reasonable opportunity" from becoming a legal argument after the fact.
One plan, structured with client-specific annexes rather than dozens of separate documents. A single core playbook covers containment and internal response, while a per-client notification map handles the differences in contract terms and regulatory regime, which keeps the plan maintainable as the client book grows or changes.
Break-glass credentials give a defined path to emergency access when normal privileged accounts are locked down or under suspicion during containment, and the plan specifies exactly when they're used, by whom, and how that use is logged and reviewed afterward. Without that documentation, the emergency access created to stop an incident can itself become something an auditor or a client later questions.
Most policies require the carrier to be notified early, often before certain remediation steps are taken, because many policies also dictate which forensics and legal vendors are covered under the panel. The plan should name that requirement explicitly so a technician mid-containment doesn't accidentally jeopardize coverage by acting before the carrier is looped in.
