Sophos vs. SentinelOne

More layers to stop threats early

Sophos Endpoint reduces exposure before investigation is needed with layered attack surface reduction capabilities, including web protection, category-based web and application control, and data control.

Protection starts later in the attack chain

SentinelOne's detection-first approach emphasizes identifying malicious behavior once suspicious activity is already underway, which can give threats more opportunity to execute before they are stopped.

Sophos Fusion

Sophos brings endpoint, network, email, cloud, identity, threat intelligence, MDR analysts, AI, and third-party integrations together as one coordinated cyber defense system.

No equivalent cyber defense system

SentinelOne is endpoint-centric and lacks a comparable cyber defense system, requiring separate tools for firewall, NDR, email security, and broader coverage.

Protection that adapts during attacks

Adaptive Attack Protection dynamically raises endpoint defenses when hands-on-keyboard activity is detected, while Critical Attack Warning alerts customers to signs of estate-wide attacks.

No equivalent documented capability

SentinelOne lacks equivalent context-sensitive defenses that automatically elevate protection during an active attack.

Local and remote ransomware protection

Sophos CryptoGuard monitors file activity regardless of source, helping stop ransomware running locally or remotely and automatically rolling back affected files.

Focused on local process behavior

SentinelOne focuses on local process behavior, which can miss ransomware running from a remote device and encrypting files over a share. Its rollback is constrained by Windows VSS limitations.

60+ exploit mitigations

Sophos applies more than 60 exploit mitigations by default to every running process, helping block techniques attackers and AI agents use to turn vulnerabilities into compromise.

Mitigation breadth not listed

SentinelOne’s anti-exploit capability focuses on memory exploits and fileless attack techniques, but the vendor does not list the supported exploit mitigations.

Broader ecosystem coverage

Sophos XDR and MDR connect with 500+ security tools, giving teams wider visibility and richer context to investigate and respond across their environment.

Fewer third-party integrations

SentinelOne’s marketplace lists about 160 third-party integrations. Its comparatively smaller ecosystem can limit coverage across diverse security stacks.

More complete MDR

Sophos MDR supports broad third-party integrations, hands-on-keyboard response, direct analyst access, and MDR Plus with critical incident management.

More constrained MDR model

SentinelOne Wayfinder MDR Elite includes an IR retainer with limits on hours and/or incidents, and additional costs may apply during an incident.

Consistent independent proof

Sophos regularly participates in and performs strongly across leading third-party tests, including SE Labs, MITRE and others, giving customers independent validation of protection outcomes.

Less consistent test participation

SentinelOne has a less consistent third-party testing record, with limited participation outside MITRE, no participation in the 2025 MITRE ATT&CK Evaluation, and selective participation in SE Labs tests.

Broader support coverage

Sophos Endpoint includes 24x7 English technical support as standard, with local language support during local business hours in selected languages.

More limited support and UI language coverage

SentinelOne endpoint plans include 9x5 support unless 24x7 is purchased separately, and the management console is available only in English and Japanese.
