SIEM or XDR? Yes

Same logs, two places, overlapping outcomes. It's time to rethink the SIEM vs. XDR question. In my last blog, I asked where XDR fits into the SIEM-less conversation. To answer that, start with the endpoint. If every threat could be stopped there, there would be less need for detection and response products such as endpoint detection and response (EDR). But attackers got better at evading even the most robust endpoint security, for example by abusing dual-use tools in living-off-the-land (LOTL) attacks.

Sophos Helps Organizations Secure the AI-Era Network as Demands on Performance and Protection Grow

New innovations give organizations greater visibility and control over AI use, deliver up to 4X higher protected throughput, and strengthen network detection and response across increasingly complex environments.

Sophos NDR Overview: AI-Powered Network Detection and Response

The network's changed rapidly, with distributed users, data everywhere, and many connected assets unable to run an endpoint agent. At the same time, adversaries are using automation and stolen credentials to evade prevention. Sophos NDR (Network Detection and Response) provides complete visibility across managed, unmanaged, and agentless assets to catch threats wherever they move.

Securing the AI-era network: Why performance and defense now belong together

Secure the AI-era network by combining high-performance protection, deeper visibility across every environment, and coordinated response that stops fast-moving threats sooner. AI doesn’t operate in isolation. Its prompts, workflows, data exchanges, and API calls all depend on the network. As organizations put AI to work, it adds a new layer of traffic that is increasingly encrypted, application-driven, and machine-to-machine.

How Hackers Steal Your Microsoft 365 Session | Sophos Threat Case

Most phishing attacks go after credentials. Evil Tokens targets something more powerful: an already authenticated Microsoft 365 session. Watch Marlene Jones break down how session theft works and how Sophos MDR stopped this real-world attack before the stolen token could be abused.

PII and third-party apps: Don't trust, verify

You have likely heard the old Russian proverb: “доверяй, но проверяй.” It means “trust, but verify,” and it used to be a standard within the InfoSec community for decades. Slowly, many organizations have moved their infrastructure toward a Zero Trust Architecture, which has helped improve security postures further. But even still, unearned and unverified trust is rampant.
