Antivirus (and next-gen AV/EPP) focuses on prevention — blocking malware before it runs. Endpoint Detection and Response (EDR) assumes some threats will get through, so it continuously records what's happening on each device, detects suspicious behaviour, and gives you the tools to investigate and respond — isolating a host, killing a process or rolling it back. In practice the two work together: prevention reduces the volume, EDR catches and contains what slips past.

EDR focuses on endpoints — laptops, servers and devices. XDR (Extended Detection & Response) broadens that view by correlating signals across endpoints plus network, email, identity and cloud, so a multi-stage attack that touches several areas is seen as one incident rather than scattered alerts. XDR gives wider context, while EDR remains the endpoint core — we help you decide how far you need to go.

EDR is a tool — it needs skilled people to tune it, hunt threats and respond, ideally around the clock. If you have a capable security team, running EDR in-house gives you full control. If you don't, Managed Detection & Response (MDR) lets a vendor's 24×7 SOC operate it for you — which is often better value and faster than building that capability yourself. We help you weigh the two honestly.

It depends on your risk and what you must protect. NGAV stops a lot, but it can't show you what an attacker did after a breach or help you respond. As you grow, hold sensitive data, or face compliance expectations, the visibility and response EDR provides become important — and reduce the time threats go undetected. For smaller, lower-risk setups, strong NGAV may suffice; we help you find the right line.

It can help. CERT-In directions set expectations around security logging and timely incident reporting, and the DPDP Act covers personal data — EDR's telemetry, alerting and forensics support detecting, investigating and reporting incidents. Where your console and logs are hosted can also matter. Pricing is typically per endpoint per month, rising from EDR to XDR to fully managed MDR. Figures here are illustrative, and this is general guidance, not legal advice — confirm specifics with the vendor and your advisors.
