About Sophos
In my evaluation of Sophos Intercept X, its deep learning neural network detected unknown zero-day malware without relying on signatures, while its CryptoGuard technology intercepted and rolled back malicious disk encryption instantly. Synchronized Security shares threat intelligence between firewalls and endpoints. The administrative cloud console can feel dense for complete novices managing mixed legacy operating systems. Supported by optional 24/7 Managed Detection and Response (MDR), it is the most reliable endpoint defense suite for mid-market organizations.
Sophos is a British cybersecurity company founded in 1985 in Abingdon, Oxford, England \u2014 one of the world\u2019s longest-established endpoint security vendors. Taken private by US private equity firm Thoma Bravo for $3.9 billion in March 2020, Sophos serves 600,000+ customers through 53,000+ channel partners and MSPs globally, with $1B+ revenue in 2023. In early 2025, Sophos acquired Secureworks for $859 million, adding the Taegis XDR/MDR platform and approximately 1,600 employees to form a combined company of ~6,000 staff.
Sophos\u2019s flagship product is Intercept X (transitioning in 2026 to \u201cSophos Endpoint\u201d branding) \u2014 a deep learning AI endpoint security platform combining next-generation antivirus, CryptoGuard anti-ransomware with automatic file rollback, 30+ exploit prevention techniques, and EDR/XDR in higher tiers. Its signature Synchronized Security technology creates a bidirectional heartbeat between Sophos Endpoint and Sophos Firewall: when a threat is detected on an endpoint, the firewall automatically isolates it from the network without any manual action. Sophos MDR \u2014 serving 25,000+ customers \u2014 provides 24/7 fully managed detection and response where Sophos analysts neutralize threats on behalf of customers. In August 2026, Sophos launched Sophos Fusion \u2014 a unified data layer consolidating endpoint, SIEM, MDR, and XDR capabilities on a single platform.
Sophos is the right choice for mid-market organizations and MSP-managed environments that want strong endpoint AI protection, automated firewall-endpoint integration, and an optional managed MDR service that eliminates the need for an in-house SOC \u2014 particularly those already running Sophos firewalls and wanting the full Synchronized Security ecosystem benefit.

Frequently Asked Questions
Sophos Intercept X (now transitioning to Sophos Endpoint) is the core endpoint security product with deep learning AI malware detection, CryptoGuard anti-ransomware, exploit prevention, and EDR. Sophos XDR extends this with cross-product telemetry across endpoint, firewall, email, cloud, and identity. Sophos MDR is the fully managed 24/7 service where Sophos analysts run detection and response on your behalf. These three stack on top of each other.
Synchronized Security is Sophos’s proprietary integration between Sophos Endpoint and Sophos Firewall via a Security Heartbeat. When a threat is detected on an endpoint, the Sophos Firewall automatically isolates that endpoint from the network without manual intervention. Conversely, firewall-detected threats trigger endpoint-level responses. This bidirectional automation is unique to the Sophos ecosystem and provides rapid automated containment.
In early 2025, Sophos acquired Secureworks, an XDR and MDR vendor, for $859 million. This added Secureworks’ Taegis platform and its enterprise MDR customer base to Sophos, expanding Sophos’s MDR market reach upmarket. In August 2026, Sophos launched Sophos Fusion — a unified data layer bringing together Sophos endpoint, SIEM, MDR, and XDR capabilities on a single platform.
Sophos publishes indicative pricing for 500-999 user, 36-month contracts: Intercept X Advanced ~$30/user/year, Intercept X Advanced with XDR ~$53/user/year. MDR service runs approximately $8-12/endpoint/month. All final pricing requires a quote from Sophos or a channel partner, with volume discounts for larger deployments.
Sophos is particularly strong for mid-market organizations and MSP-managed environments. With 53,000+ channel partners, Sophos is designed to be deployed and managed by MSPs and resellers. Its Synchronized Security firewall-endpoint integration, straightforward Sophos Central management, and MDR service make it a strong fit for organizations without a dedicated in-house SOC.
