Managed service providers (MSPs) need more than monitoring: they and their customers must be ready to contain incidents, keep essential operations going, and restore systems and data. An MSP’s privileged access and connections across multiple customer environments can make a provider incident a source of downstream risk. Detection matters, but it cannot substitute for controlled access, protected backups, exercised response plans, and clear decisions about who does what.
Why monitoring alone is not enough
Monitoring can help identify suspicious activity, but an alert does not by itself limit an intruder’s access, recover corrupted data, or tell customers who is authorized to shut down a system. Resilience means preparing for disruption, adapting as conditions change, and withstanding and recovering from adverse events. CISA describes resilience in those general terms; it is not an MSP-specific certification or guarantee. CISA’s resilience services overview

The provider-customer relationship adds a particular challenge: provider accounts, tools, and network connections may reach into customer environments. A compromise affecting an MSP can therefore expose more than the provider’s own systems. A 2022 joint government advisory warned of this downstream risk and urged MSPs and customers to protect their networks. Joint advisory on risks to managed service providers and their customers

Four operational pillars for MSP cyber resilience
1. Control provider identities and privileges
Require multifactor authentication for provider access where possible, and give accounts only the permissions needed for their assigned work. Review access regularly, including accounts used by technicians, automation, and vendors. These steps can reduce exposure; they cannot eliminate the possibility of compromise. Joint MSP advisory
2. Review connections and customer boundaries
Map how provider tools and systems connect to each customer environment. Assess whether each connection is necessary and what it can reach, rather than assuming that a single network boundary adequately separates provider and customer systems. Include these relationships in architecture reviews and supply-chain risk management. Joint MSP advisory
3. Protect backups and prove restoration works
Backups are useful only if they remain available and can be restored. CISA recommends protecting backup data from the systems it is meant to recover, including by using isolated storage, maintaining backups, and testing them regularly. The appropriate backup frequency depends on the customer’s recovery point objective (RPO)—how much recent data the organization can afford to lose. Joint MSP advisory and CISA backup options

An external drive can serve as one offline backup medium if it is disconnected and otherwise protected appropriately. A drive alone is not a backup strategy: coverage, isolation, account and key access, encryption, retention, and tested restoration all matter. NIST’s backup guide offers technical considerations for organizations assessing backup approaches. NIST NCCoE data integrity and backup options
MSPs should maintain backups of their own data and, where the service agreement makes it appropriate, customer data. In either case, identify who controls backup accounts and encryption keys, how copies are separated from production access, and how often restoration is exercised. Do not treat an untested backup as proof that recovery is achievable.
4. Exercise response and recovery plans
Plans need named roles and practiced decisions, not just a list of technical steps. MSPs and customers should identify who handles technical investigation, executive decisions, procurement or vendor coordination, customer communications, containment, and restoration. Exercise the plan together so participants understand how responsibilities fit across organizational boundaries. Joint MSP advisory

Service discussions and contracts should make update, backup, incident-notification, and recovery responsibilities understandable. Customers should know the provider’s update policy and agree on appropriate response and recovery requirements. The exact commitments depend on the service relationship; no single contract term guarantees a successful recovery. Joint MSP advisory

What customers should keep independent
Customers should retain their own offsite copies of essential records and network activity logs. Independent logs can help an organization check vendor activity and support incident forensics; they should not be assumed to replace the MSP’s records or monitoring. CISA also recommends including key vendors such as MSPs in incident-response and business-continuity planning, and updating plans when vendor relationships change. CISA customer risk considerations for MSPs
Independent copies and records give the customer information and recovery options beyond the provider’s systems. Their value depends on whether they are accessible, protected, sufficiently current, and usable when normal systems are disrupted.

Questions to ask an MSP—and evidence to request
Use these questions to make responsibilities and recovery assumptions concrete. Ask for evidence such as a recent restore exercise or a documented access review, while recognizing that a demonstration does not guarantee the outcome of a future incident.
- Coverage: Which customer systems, data, and configurations are backed up, and which are not?
- Isolation: How are backup copies separated from production systems and the provider accounts that administer them?
- Control: Who can access backup accounts and encryption keys? What happens if the provider’s administrative environment is compromised?
- Testing: When was restoration last exercised, what was restored, and what issues were found?
- Recovery objectives: What RPO and recovery time objective (RTO)—the target time to restore service—does the arrangement support, and how do those targets relate to the customer’s operational needs?
- Incident decisions: Who notifies whom, who can authorize containment, and who decides when systems are safe to restore?
- Shared responsibilities: Which party handles updates, backups, incident notification, customer communications, and continuity planning?
- Customer-held records: What essential records and network activity logs will the customer retain independently, and how will they be accessed during an incident?
When comparing approaches or provider commitments, assess isolation, critical-system coverage, restore testing, access and key control, retention, and fit with recovery objectives. The cited government and NIST materials provide practices and considerations, not vendor rankings or a best-product recommendation.
A practical first exercise
Choose one realistic disruption scenario with the MSP and customer—for example, loss of access to a critical system—and walk through the response from detection to restoration. Assign decision-makers, confirm notification paths, identify the backups and customer-held records needed, then test a restoration against the customer’s recovery objectives. Record gaps and owners for fixing them. A focused exercise turns broad promises about recovery into specific work the two organizations can verify.
