Here's the uncomfortable truth about being a CISO right now: you're expected to prevent breaches that haven't been invented yet, explain complex technical risks to boards in business language, manage security budgets under constant scrutiny, and stay current on threats that evolve faster than you can read about them.
That’s a lot of work for one person. Good thing you don’t have to figure it out alone.
The best CISOs are voracious learners who tap into a carefully curated network of thought leaders, practitioners, and researchers who've already navigated similar challenges. They know which voices cut through the noise and which sources waste precious time.
This guide identifies the 25 most valuable blogs for security leadership in 2026—not the biggest, not the flashiest. These are the blogs (and some newsletters and podcasts thrown in for good measure) that consistently deliver insights that matter. They’re authentic voices from practitioners, researchers, and leaders tackling the real challenges you face every day.
We selected these blogs based on five criteria:
- Strategic relevance – Addresses leadership, governance, and business alignment
- Practitioner credibility – Written by people doing the work, not just covering it
- Actionable insights – Provides frameworks you can actually implement
- Consistent quality – Maintains editorial standards over time
- Diverse perspectives – Covers technical depth, policy, culture, and leadership
You'll find resources for every aspect of modern security leadership: threat intelligence for risk discussions, governance frameworks for board presentations, leadership lessons from peers, technical deep-dives for SOC maturity, and strategic thinking for long-term program development.
How to Use This Guide
Don’t try to follow all 25 blogs at once. Start with three to five that match your current priorities, whether that’s board communication, AI-driven defense, or building a stronger security culture. Subscribe to their newsletters or RSS feeds, and schedule 30 minutes each week for strategic reading.
This small, consistent habit compounds fast. The CISOs who make time for continuous learning and peer insights consistently outperform those who focus only on operational execution. Treat this list as part of your professional development infrastructure—not a nice-to-have, but a strategic advantage.

Trends That Matter to CISOs for 2026 and Beyond
As you explore the blogs and thought leaders featured in this guide, you'll notice recurring themes that signal where cybersecurity leadership is heading. These aren't buzzwords or vendor hype; they're fundamental shifts in how security programs operate, how CISOs communicate value, and how organizations defend against evolving threats.
Here are the critical trends shaping the CISO role for 2026 and beyond:
AI as Both Weapon and Shield
Artificial intelligence has moved from experimental to operational in cybersecurity. As highlighted by experts like Daniel Miessler and Anton Chuvakin, AI is simultaneously enabling attackers to scale operations with minimal technical skill while giving defenders new tools for detection and response.
Daniel Miessler already expressed concerns about this in a 2023 post on his blog, saying, “In the early days of AI, attackers will be able to use AI to automate attacks while defenders still lack context about their environment. They don’t have AI deployed yet that understands their networks, their applications, their users, and their company’s policies. I expect this to last 3-5 years, even for the fastest-moving organizations.”
The Shift from Technical Expert to Business Translator
The blogs from Phil Venables, CISO Series, and CSO Online emphasize a fundamental evolution: today's CISO must be as fluent in business language as in technical terminology. Security leaders who can't articulate cyber risk in terms of business impact, revenue protection, and strategic enablement won't survive.
Indeed, Phil Venables says in a Google Cloud CISO Perspectives post, “By discussing the consequences of cyber-attacks at the executive and board-level in terms of the business impact, we’re making ourselves more understandable to crucial stakeholders — and more likely to find them in agreement with us.”
Identity as the New Perimeter
With cloud adoption, remote work, and distributed architectures now permanent, experts like Troy Hunt and Graham Cluley consistently emphasize that identity and access management have become the critical battleground. Traditional network perimeters are extinct.
Supply Chain Security as Existential Risk
From CIS to SANS Institute to Krebs on Security, the message is clear: your security is only as strong as your weakest vendor. Supply chain attacks have evolved from rare exceptions to the standard adversary playbook.
The Board Expects Security, Not Excuses
As George Finney (CISO Series) and others note, boards are no longer accepting "security is hard" as an explanation for failures. They're asking harder questions, demanding quantifiable metrics, and holding CISOs accountable for business outcomes.
Threat Modeling and Proactive Design
Adam Shostack's emphasis on threat modeling reflects a broader shift: reactive security is no longer sufficient. Organizations that bake security into system design outperform those that bolt it on afterward.
In his “Ultimate Beginner’s Guide to Threat Modeling,” Adam Shostack makes this clear, saying “Threat modeling can help you find design and security issues. When you do this before you even write a line of code, you can fix the problem proactively, saving time and money.”
Security Culture as Competitive Advantage
PECB, John Masserini, and other practitioners emphasize that technology alone won't save you—culture determines outcomes. Organizations with strong security cultures outperform those that rely solely on controls.
In a PECB article from 2021, CIO and InfoSec veteran Don Baham makes this point clear, saying “It is all well and good adopting state-of-the-art, advanced security technology and tools to protect your company data and systems from cyber threats. But if you fail to establish a strong cybersecurity culture, you will still be vulnerable.”
Regulatory Complexity and Global Compliance
Resources like Gartner and PECB International highlight how regulatory requirements are multiplying faster than organizations can adapt. SEC disclosure rules, NIS2 in Europe, state privacy laws in the US…compliance is fragmenting globally.
The Cybercrime Economy is Industrializing
Krebs on Security, Risky Business, and Threats Without Borders document how cybercrime has matured into a sophisticated economy with specialists, supply chains, and business models. Ransomware-as-a-Service, initial access brokers, and cryptocurrency laundering have industrialized attacks.
The Integration of Security, Privacy, and Ethics
As AI, biometrics, and surveillance technologies proliferate, blogs like Daniel Miessler's and Graham Cluley's remind us that security leaders must navigate ethical dimensions alongside technical ones. Privacy, transparency, and responsible technology use are now security leader responsibilities.
The Common Thread: Adaptability
If there's one meta-trend underlying all of these shifts, it's this: the CISOs who thrive are those who continuously adapt. The blogs featured in this guide are all trying to help security leaders stay ahead of change rather than react to it.
That's why following thought leaders like Phil Venables, Krebs on Security, Anton Chuvakin, and the other voices in this guide isn't optional professional development. It's essential infrastructure for security leadership.
