SentinelOne vs Sophos: EDR for MSPs

SentinelOne and Sophos both sell endpoint protection that an MSP can manage across every client from one console, but they solve the problem from opposite ends. SentinelOne builds out from an autonomous AI agent that makes containment decisions on the endpoint itself. Sophos builds out from a connected portfolio where endpoint, firewall, and a managed SOC all talk to each other. This guide breaks down detection, response, managed services, pricing, and review scores so you can pick the one that fits how your shop delivers security.

TL;DR: SentinelOne vs Sophos

How SentinelOne and Sophos Detect Threats

SentinelOne runs its detection logic on the agent. The Storyline engine maps every process, file change, and network connection into a live attack story, then scores it without waiting on a cloud query. That on-device model is the reason SentinelOne can keep protecting an endpoint that drops offline, and it is what reviewers mean when they call the agent autonomous. The trade-off is that a powerful local agent needs tuning to keep false positives down on noisy line-of-business software.

Sophos Intercept X leads with deep-learning malware classification and anti-exploit technology, backed by CryptoGuard, the feature that rolls back maliciously encrypted files. Our Sophos Intercept X review breaks down that agent in depth. Detection leans more on cloud analysis through Sophos Central than SentinelOne's on-agent approach. For an endpoint-only deployment the two land close on raw detection quality. The difference shows up in how each one behaves when you add more of the vendor's stack around it, which is the cross-product tier our Sophos XDR review digs into.

On independent testing, both have receipts but earned them differently. Sophos posted 100% detection across all 16 steps in the MITRE ATT&CK Enterprise 2025 Evaluation. SentinelOne sat out the 2025 round to focus on product work, but in the 2024 evaluation it hit 100% detection while generating 88% fewer alerts than the median vendor, which matters when alert fatigue is the thing burning out your SOC techs.

Autonomous Response: Storyline vs Synchronized Security

This is where the two philosophies separate. SentinelOne's response is agent-driven: endpoint isolation, file quarantine, process termination, and network containment all fire from the local agent, with one-click rollback to a pre-attack state on Windows and macOS. Approval can be automatic or gated. If your priority is the fastest possible containment with the least human input, this is the stronger model.

Sophos answers with Synchronized Security. The endpoint and the Sophos Firewall share a Security Heartbeat, so a compromised machine can be cut off from the network automatically through the firewall, not just quarantined on the host. Sophos also supports six autonomous actions including account disable. The catch is the one that runs through the whole Sophos story: that network-level isolation only works if you also run the Sophos firewall. SentinelOne's containment needs nothing but its own agent.

For an MSP standardized on a single endpoint vendor and a mixed bag of firewalls, SentinelOne's self-contained response is simpler to deliver. For one willing to run Sophos end to end, the firewall-plus-endpoint tie does something neither product does alone.

Multi-tenant management is the other thing that decides this for a service provider. Both run from a central console with cross-client visibility, but the day-to-day feel differs. SentinelOne's console is built around the agent and the investigation timeline, so techs working incidents tend to like it. Sophos Central spans more product categories, which is powerful for a shop selling endpoint plus firewall plus email, and heavier to learn because there is simply more in it. Map the console to whoever lives in it all day before you commit a client base to either one.

Managed Detection: Vigilance vs Sophos MDR

Most MSPs do not buy either of these just for the agent. They buy the managed SOC behind it, because nobody is staffing a 24/7 night shift on SMB margins. The MSP security stack guide lays out why a managed detection layer is now table stakes rather than an upsell.

Sophos MDR is the standout here. It carries a 4.7 out of 5 on G2 across roughly 1,500 reviews and ships in two tiers: Essentials for 24/7 monitoring and active containment, and Complete for full incident response with a named lead and a breach warranty worth up to $1 million. It is a mature, heavily reviewed service, and it is often the single biggest reason an MSP lands on Sophos.

SentinelOne answers with Vigilance Respond, its MDR add-on layered on the Singularity platform, plus a higher-touch managed service for shops that want SentinelOne analysts running response end to end. Vigilance is strong and tightly integrated with the agent, but it carries fewer public reviews than Sophos MDR. If a managed SOC with a long, visible track record is what reassures your clients, Sophos has the deeper paper trail.

One more thing MSPs should pressure-test before signing: who has authority to isolate a client host at 3 a.m., and how fast. Both services will contain a threat for you, but the response policy and the escalation path are what you are really buying. Get the SLA in writing, run a tabletop test against it, and make sure the containment actions you are delegating match what your clients have agreed to in their own contracts. The managed layer is only as good as the boundaries you set around it.

Pricing for MSPs

Both price through the channel, so your client number is partner cost plus your markup. The list figures still tell you where each one sits.

SentinelOne publishes tiers: Singularity Control runs about $80 per endpoint per year and Singularity Complete about $180, with Vigilance MDR adding roughly $15 to $30 per endpoint on top. Sophos Intercept X starts near $28 per user per year for Essentials and climbs to the $50 to $70 range for Advanced and EDR tiers, with MDR billed separately at roughly $7 to $17 per endpoint per month.

The practical read: Sophos usually comes in cheaper at the entry tier and bundles more security categories under one vendor, while SentinelOne's Complete tier is a premium EDR play you charge a premium security package for. If you want a higher-ceiling agent and can sell the markup, SentinelOne earns it. If you want broad coverage at a friendlier floor, Sophos wins on price. For where an EDR line item sits against the rest of a client build, the CrowdStrike Falcon review for MSPs covers the third name that usually rounds out this shortlist.

Reviews and Independent Testing

On aggregated buyer reviews, SentinelOne Singularity holds a 4.7 out of 5 on G2, while Sophos Intercept X sits at 4.4 out of 5 on G2, 4.5 on Capterra, and 8.9 out of 10 on TrustRadius. SentinelOne's edge on the endpoint score is real but narrow; Sophos closes the gap and pulls ahead once you weigh its 4.7-rated MDR service into the bundle.

The criticism patterns differ in a useful way. SentinelOne reviewers flag tuning effort and pricing that is hard to pin down without a quote. Sophos reviewers flag year-over-year price creep and a console with a learning curve. Neither is a dealbreaker, but both tell you to scope the deployment and write renewal terms before a marquee client goes live. For a deeper look at SentinelOne in an MSP context, the SentinelOne review for MSPs goes further on multi-tenant management and where the agent fits.

SentinelOne vs Sophos: Which Should an MSP Pick?

Pick SentinelOne if endpoint detection and autonomous response are the job and you want the highest agent ceiling on the shortlist. Its on-device model contains threats fast with minimal human input, the 2024 MITRE numbers are excellent, and the 4.7 G2 score backs it up. You pay more at the Complete tier, and you sell that as a premium security package.

Pick Sophos if you want one vendor covering endpoint, firewall, and a battle-tested managed SOC from a single console, at a friendlier entry price. The MDR service is the deciding factor for a lot of MSPs, and Synchronized Security does something across the portfolio that a single-agent vendor cannot match. If Sophos is the side you are leaning toward, weigh it against the wider field in our Sophos alternatives roundup.

The real split: SentinelOne is the sharper point tool, Sophos is the broader platform. Decide which problem you are actually solving, then buy the one built for that problem, not the one with the louder marketing.
