✅ Runs every day at 6:00 AM IST (customizable) ✅ Collects from 15+ sources (CVEs, news, cloud bulletins) ✅ Filters for relevance (High/Critical severity only) ✅ Deduplicates across sources ✅ Generates AI summaries with persona-based insights ✅ Creates beautiful Notion entries ✅ Takes 2-3 minutes to run ✅ 100% free - uses only free tiers
- NVD API - CVEs with CVSS >= 7.0
- GitHub Advisory Database - Security advisories
- Krebs on Security - Industry-leading journalism
- BleepingComputer - Breaking news
- The Hacker News - Daily security updates
- Dark Reading - Enterprise analysis
- AWS Security Bulletins - Cloud vulnerabilities
- GCP Security Bulletins - Google Cloud updates
- arXiv - Research papers
- Exploit-DB - POC exploits
- CERT - Coordinated disclosures
For each security item, generates:
-
WHAT - Plain language description (2-3 sentences)
-
WHY IT MATTERS - Persona-specific insights:
- For Security Engineers: Technical implications, action items
- For GRC Teams: Compliance impact, reporting requirements
- For Data Privacy Officers: Data protection implications
-
Metadata: Estimated read time, tags, regions, severity
- Beautiful, mobile-friendly entries
- 9 pre-configured views (by persona, severity, region)
- Full-text searchable
- Filterable by tags, categories, CVE IDs
- ~10 minute daily reading time
- Offline access via Notion mobile app
- GitHub account
- Notion account
- Groq API key (no credit card)
- Optional: NVD API key (for higher rate limits)
Step 1: Get API keys (Groq, Notion) Step 2: Create Notion database with provided schema Step 3: Fork repo and add secrets to GitHub Step 4: Run workflow manually to test Step 5: Enjoy daily digests automatically!
Detailed instructions: See SETUP.md
Problem: Traditional security newsletters just dump headlines with no context.
Solution: Every item includes persona-based "why it matters" insights:
- Security engineers get technical implications
- GRC teams get compliance impact
- Privacy officers get data protection considerations
No competitor does this.
Problem: Email digests are cluttered and hard to read on mobile.
Solution: Notion provides:
- Clean, organized interface
- Perfect mobile experience
- Searchable archive
- Custom views per persona
- Offline reading
Problem: Commercial tools cost $50-500/month.
Solution:
- Free GitHub Actions (2000 min/month, use ~5 min/month)
- Free Groq API (~500K tokens/day, use ~15K/day)
- Free Notion (generous free tier)
- Free data sources (RSS, public APIs)
Total cost: $0/month
Problem: Self-hosted tools require servers and updates.
Solution: GitHub Actions handles everything:
- No servers to maintain
- No updates to deploy
- No monitoring required
- Just fork and forget!
Problem: Commercial tools have rigid formats.
Solution:
- Add your own RSS feeds (config.yaml)
- Customize AI prompts (security_digest.py)
- Change schedule (GitHub Actions)
- Modify Notion views (Notion UI)
- Open source = infinite flexibility
Problem: Commercial tools are closed ecosystems.
Solution:
- MIT License (use anywhere, modify freely)
- Clean, documented code
- Easy to contribute
- Community-driven improvements
- Build your own features
Analyzed 13 open-source security tools:
- OpenCVE (enterprise, complex setup)
- IntelOwl (threat intel platform, 200+ analyzers)
- ThreatIngestor (modular framework)
- Huginn (self-hosted IFTTT)
- Others...
Key finding: NONE have AI summarization + beautiful UX + pre-configured feeds + zero setup.
Market gap identified ✅
