Why ASecurityGuru

Built by a practitioner.
For practitioners.

Not a news aggregator. Not a vendor blog. Real security intelligence from someone who has worked in the trenches.

01
CISA KEV — Not Just NVD
Most CVE trackers show you everything in NVD — 350,000+ entries, mostly theoretical. We prioritise CISA's Known Exploited Vulnerabilities list — only CVEs confirmed being used in real attacks right now.
02
Expert Context on Every Alert
Every CVE and news item includes Raghu's expert take — what it means for your organisation, what to do first, and how severe it really is beyond the CVSS score.
03
100% Free, No Login Required
No paywalls. No registration. No email required to access the tools. Professional-grade security intelligence should be accessible to everyone — especially defenders with limited budgets.
