CrowdStrike vs SentinelOne for IT Consulting and MSPs

Attackers targeting MSPs know that compromising one technician's machine can be more efficient than attacking each client directly. A single technician with remote monitoring and management access into twenty client networks is, from an attacker's perspective, twenty targets behind one door. That is the reasoning behind treating your own staff endpoints with the strictest policy in your fleet, stricter than anything you would deploy for a typical client end user, because the blast radius of a technician laptop compromise is measured in clients, not files.

Both CrowdStrike and SentinelOne offer multi tenant management built for MSPs, letting you see and manage policy across client environments from one console rather than logging into each client's instance separately. Decide early whether you will run one shared tenant across all clients or separate tenants per client, since retrofitting that decision later means re deploying agents. A shared tenant is faster to manage day to day. Separate tenants make it easier to hand a client full visibility into just their own environment, which some clients will ask for directly.

Do not let the same credential that gives a technician remote access into a client network also be the credential that can disable or modify EDR policy on that client's endpoints. If a technician's account is compromised, you want the attacker to be able to do damage in one direction, not both attack the client's systems and blind your own detection of that attack at the same time. Keep EDR administration on a separate, more tightly controlled account than day to day remote access, even for the same technician.

If your MSP already runs a security operations function, even a lean one, self managed SentinelOne across your client base can work well: your own analysts get an autonomous agent that does more containment on its own before they even get involved. If you do not have that function and do not plan to build it, CrowdStrike's Falcon Complete effectively rents you one, a managed team watching alerts across your fleet, which some MSPs then resell to clients as part of their own managed security offering.

Clients increasingly ask their MSP for a written incident response plan before signing, not just a list of tools. Whichever platform you choose, document specifically: how an alert reaches your team, how fast a compromised endpoint gets isolated, how a client gets notified, and who decides whether law enforcement or a client's own leadership needs to be looped in. That document, not the vendor name on your invoice, is usually what a prospective client's own security review is actually asking for.

What a client-ready incident response plan should document:

• How an alert reaches your team, including who receives it and what happens when the first person does not respond.
• How quickly a compromised endpoint gets isolated once it is confirmed, stated as a specific commitment rather than a general promise.
• How and when a client is notified if one of their systems is affected by an incident on a technician's machine.
• Who can change or disable EDR policy, kept separate from the credentials technicians use for remote access into client networks.

A written incident response plan that has never been tested is a guess dressed up as a procedure. Once you have chosen a platform and drafted the plan, run a tabletop exercise: pick a realistic scenario, a compromised technician laptop with access to several clients, and walk your team through exactly what they would do, in what order, using the console you actually deployed. This usually surfaces gaps a document review misses, like nobody actually knowing which manager has authority to notify a client at two in the morning, or a step in the plan that assumes access to a system that is itself down during the incident.

Run this exercise at least once a year and after any major change to your client roster or your own staffing, since a plan written for a five client MSP does not automatically scale to twenty clients without someone checking that the same response times are still realistic. Clients who ask for your incident response plan sometimes also ask when you last tested it, and having a real answer says more than the document itself.
