Cybersecurity buyers want more than product pitches. They want evidence, context, and insight. David D. Geer: linkedin.com/in/daviddgeer/

Want a better cybersecurity first draft? Give the writer more than keywords. Share the actual story, audience, POV, evidence, intended outcome, and publication context. David D. Geer: linkedin.com/in/daviddgeer/

Identity is more than login credentials. Cloud access, tokens, and service identities are expanding the enterprise attack surface. David D. Geer: linkedin.com/in/daviddgeer/ #CybersecurityWriter #B2BCybersecurityWriter #InfosecWriter

A strong cybersecurity byline should answer: What changed? Why does it matter? What should buyers ask next? David D. Geer: linkedin.com/in/daviddgeer/ #ThreatIntelligence #CybersecurityWriter

“AI-powered” is a product claim not the complete product story in cybersecurity. What does the capability actually do? What problem does it solve? What evidence supports it? And why should the buyer care? David D. Geer: linkedin.com/in/daviddgeer/ #AISecurity

Quantum is not a future issue. NIST recommends that organizations move to post-quantum cryptography due to "harvest now, decrypt later" threats, among others. The problem: explaining post-quantum cryptography to enterprise buyers. David D. Geer: linkedin.com/in/daviddgeer/

Your Zero Trust story can be technically strong and still lose the buyer. The key is turning complex architecture into a clear, credible story that decision-makers understand. David D. Geer: linkedin.com/in/daviddgeer/ #ZeroTrust #CybersecurityWriter #B2BCybersecurityWriter

One compromised password can expose more than one account, especially when someone or something reuses those credentials. Use long, unique passwords, a trusted password manager, and MFA. Stay alert for unexpected login requests. David D. Geer: linkedin.com/in/daviddgeer/

“I'm too small to get hacked.” Threat actors: “Challenge accepted.” Small businesses can still face risks from weak passwords, outdated software, exposed accounts, and human error. Never assume small means secure. David D. Geer: linkedin.com/in/daviddgeer/

AI-powered scams can look convincing. Watch for deepfakes, urgency, unusual requests, suspicious links, changes in communication style, and attempts to bypass normal procedures. When in doubt, verify through a trusted channel. David D. Geer: linkedin.com/in/daviddgeer/

Cybersecurity requires layers of defense. Which would you consider the strongest first line of defense? 1. Employee Awareness 2. AI-Based Security 3. MFA 4. Security Monitoring Vote and share your perspective.

Traveling? Think twice before using public Wi-Fi for sensitive accounts. Use mobile data when possible, verify HTTPS, and avoid automatic Wi-Fi connections. Stay secure wherever you work. David D. Geer: linkedin.com/in/daviddgeer/

AI is changing the cyber threat landscape from AI-assisted phishing and automated attacks to deepfakes and faster analysis of stolen data. Organizations need defenses that keep pace. For authoritative content, reach David D. Geer: linkedin.com/in/daviddgeer/ #AISecurity

Small digital habits can create big security risks. Reused passwords, skipped updates, unverified links, and oversharing can all increase your exposure. Build better security habits with awareness. David D. Geer: linkedin.com/in/daviddgeer/

Pause before you click. Verify links and attachments independently before opening them. A few seconds of caution can prevent a major security incident. David D. Geer: linkedin.com/in/daviddgeer/ #CybersecurityAwareness #SecurityAwareness #CybersecurityWriter

The updated paper on gating autonomous AI agents is now live on HackerNoon. After deep discussions across r/devsecops & r/cybersecurity, I merged structural updates, expanded threat models, and clearer architecture diagrams. Over 8 hours of read time logged, 4 reads to 200.

Secondary LLM reviewers are not security boundaries. If indirect prompt injection tricks the primary model, a secondary LLM reviewing the same context fails identically. Infrastructure edge controls must be deterministic.

Let the model handle problem-solving, but force tool execution through deterministic gateways. Read the full updated paper on HackerNoon: hackernoon.com/the-vulnerabi… How is your team handling boundary controls for agentic workflows? 👇

😄 Strong Passwords Matter More Than Ever Weak passwords remain one of the easiest ways attackers gain access. Instead of using predictable passwords: ✔Create unique passwords ✔Use a password manager ✔Enable MFA 🔗 davidgeer.com/ #CybersecurityAwareness #MFA
