questions answered
Q.What is the difference between antivirus and EDR for business?
Traditional antivirus (AV) works by matching files against a database of known malware signatures. It is reactive and misses novel threats. Endpoint Detection & Response (EDR) is a next-generation approach that monitors all endpoint behaviour in real time, detects anomalies and suspicious patterns, responds automatically to contain threats, and provides forensic investigation capabilities. Most UK cyber insurers now require EDR rather than traditional AV for SME policies. Coreitech recommends EDR for all business clients and can deploy Microsoft Defender for Business (included in M365 Business Premium) as the most cost-effective solution.
Q.Do I need antivirus for Windows PCs in a business?
Yes — and more than just antivirus. Windows Defender (built into Windows 11) provides baseline AV protection, but for business use Coreitech recommends Microsoft Defender for Business (EDR-tier, included in Microsoft 365 Business Premium at £19.80/user/month) or a third-party EDR solution. For Cyber Essentials, all devices must have: malware protection enabled and up to date, real-time scanning active, and auto-updates configured. Basic Windows Defender alone can satisfy Cyber Essentials, but EDR provides significantly stronger protection for the same cost (if already using M365 Business Premium).
Q.What antivirus do UK businesses use?
The most commonly deployed endpoint security solutions in UK SMEs are: Microsoft Defender for Business (via Microsoft 365 Business Premium) — rapidly growing due to M365 adoption; Sophos Intercept X — popular with SMEs using Sophos firewalls; SentinelOne — increasingly common in regulated sectors; ESET — popular in professional services. Coreitech manages all of these and recommends Microsoft Defender for Business as the default for M365-using clients due to the price/performance ratio.
Q.Is free antivirus good enough for a business?
No. Free antivirus products (AVG Free, Avast Free, Malwarebytes Free) lack central management consoles, policy enforcement, security event logging, and the EDR capabilities required by cyber insurers and Cyber Essentials. They also typically lack business support SLAs. For any UK business with more than 3 employees, a centrally managed business endpoint security solution is required. Microsoft Defender for Business is included in Microsoft 365 Business Premium at £19.80/user/month and provides enterprise-grade EDR.
Q.How much does business antivirus/EDR cost in the UK?
Business endpoint security costs in the UK: Microsoft Defender for Business (EDR): included in M365 Business Premium at £19.80/user/month (also includes Teams, Exchange, SharePoint, OneDrive, Intune MDM); SentinelOne Singularity Go: from £4/device/month; CrowdStrike Falcon Go: from £5/device/month; Sophos Intercept X: from £4/device/month; ESET Protect: from £3/device/month. Coreitech deploys and manages all of these — management included in our Standard (£25/user/month) and Advanced (£50/user/month) managed IT packages.
