Microsoft's recent benchmarking data suggests that its Defender for Office 365 catches the vast majority of malicious and spam emails, leading the company to claim that additional email security tools may not be necessary. However, experts are advising businesses to be cautious of such vendor claims.
What Happened
Microsoft's quarterly benchmarking data revealed that its integrated partners improve the catch rate of malicious emails by less than 0.05%. This has led the company to suggest that a one-vendor email security stack may be sufficient for businesses. However, experts are urging caution, pointing out that no single solution can guarantee 100% protection against cyber threats.
Why It Matters
The security community is concerned about the potential risks of relying on a single email security tool. As Seva Ioussoufovitch, senior research analyst at Info-Tech Research Group, noted, "A layered 'defense in depth' strategy that incorporates multiple tools is still the best approach to ensuring robust email security."
What Experts Say
Experts are also warning about the dangers of fileless malware, which can execute entirely in memory and evade detection. The Fileless Phantom Stealer is one such example, which targets browser credentials and uses anti-analysis techniques to frustrate detection.
