Sophos Security users list

Email list of companies using Sophos Security

Q: How many companies use Sophos Security?

Data InfoMetrix tracks 142,800 companies using Sophos Security, with 940,351 verified contacts at those accounts as of October 2026. The largest groups are Education, Healthcare and Manufacturing SMBs. Counts are estimates from our database and market research, so ask us for a live count for your exact criteria.

Q: Who buys and manages Sophos Security inside a company?

Sophos Security is usually owned by SMB & Mid-Market Endpoint, Firewall and MDR. Decision-makers include IT Director, CTO and Head of IT; IT Manager and Systems Administrator shape the choice, and Systems Administrators and Network Administrators use it day to day. Our Sophos Security list can include any of these roles.

Q: Which Sophos Security products or editions can I target?

You can target accounts by the Sophos Security products they run, including Sophos Intercept X, Sophos MDR, Sophos XGS Firewall, Sophos Central and Sophos XDR (with Secureworks Taegis). Tell us which edition or module matters and we filter the list to those accounts.

Q: What other software do Sophos Security customers use?

Sophos Security customers commonly also run Microsoft 365, Windows Server, ConnectWise, Veeam and Datto. Sophos Security is often connected to Azure, so users of those tools overlap heavily. We can filter any list by this kind of stack overlap.

Q: What are the main alternatives to Sophos Security?

The main alternatives to Sophos Security are SentinelOne, CrowdStrike and Fortinet. We also keep verified user lists for SentinelOne, CrowdStrike and Fortinet, which is useful for competitive displacement campaigns.

Q: When are Sophos Security customers most likely to buy?

Buying triggers we track for Sophos Security accounts include endpoint renewal, firewall refresh, ransomware incident and MSP change. A common pain point is 24x7 monitoring without a SOC: SMBs need MDR.

Q: Can Data InfoMetrix deliver a free sample Sophos Security contact list before ordering?

Yes. Data InfoMetrix delivers a complimentary 10-record sample tailored to your target Sophos Security criteria—including target job titles, company size, and region—delivered within one business day with no obligation.

Data InfoMetrix provides a 99% email deliverability guarantee on all Sophos Security datasets. Every contact record undergoes real-time email verification within a 30 to 45-day refresh cycle, backed by a 1:1 hard bounce replacement policy for 30 days after delivery.
