For some, they’re a learning experience, for others they inspire, and for still others, they’re a great way to have fun by reading what can sometimes be an opinionated and sarcastic piece of content. Whatever the reason, reading cybersecurity blogs is a daily routine for most of us.
Here at SecurityTrails, we keep a handy list of bookmarked cybersecurity blogs to follow, and we thought it would be a good idea to share that list with you. Allow us to introduce you to a few authors you might not have encountered but will find worthwhile.
Here are our favorite cybersecurity blog posts you should be reading in 2021:
Top 10 Best Cybersecurity Blogs
In this list you’ll find small, independent researchers, respected security vendors and popular media sites. What they all have in common is that they provide value, and they do it frequently.
We’ve made sure to compile a good mix of blogs including those run by individual researchers and those that are part of larger organizations and enterprises. We would love to include even more, but rather than make you read a list of 50 blogs, we narrowed it down to 10.
Included are commentaries, news on the most recent data breaches, useful how-to tutorials and more. This list is based on all of the blogs we here have bookmarked and turn to daily for inspiration, and to share with others. If any interest you, be sure to bookmark them. We’d also like to hear about your own favorite cybersecurity blogs that didn’t make it on this list.
1. Krebs on Security
Krebs on Security is one of the most influential blogs in the field, and its author Brian Krebs has already been included in our list of 10 cybersecurity legends. Krebs is a well-known investigative journalist who covers computer security and cyber crime, earning himself many awards through the years; most recently, he was named CISO MAG Cybersecurity Person of the Year in 2019.
Surprisingly, Krebs has no formal technical background in the security field, but after being hacked by the Lion worm twice, he developed an obsession for computer security that hasn’t stopped since. The former Washington Post journalist started Krebs on Security in 2009, where he publishes investigative series on uncovering cybercrime groups, high-profile data breaches, the latest cyber threats, and details on these investigations that you can’t find anywhere else.
His high standing in the cybersecurity industry has allowed him access to key resources that have led to taking down several hacker groups. He’s also discovered various large data breaches like the ones affecting Target (also identifying the malicious actor behind it), Home Depot, Goodwill, Adobe and Ashley Madison, among others.
His expertise with the dark side of the Internet has given Krebs valuable and unique insights on the emerging threats and sophistication of cybercrime groups. And in his blog, he offers detailed security investigations on both tactics of the attack and personal information on the criminals themselves, which often puts him at risk: Krebs on Security was hit with one of the biggest DDoS attacks ever targeted to publications of its type. Still, that doesn’t change his strong sense of justice, which is viable in each of his reports. We applaud the depth, authority and consistent dash of recognisable humour in his work, which makes him one of our first stops for the best in cybersecurity news.
Our top picks for Krebs on Security blog posts:
- A Deep Dive on the Recent Widespread DNS Hijacking Attacks
- Who Hacked Ashley Madison?
- Sources: Target Investigating Data Breach
2. Schneier On Security
Described by The Register as “The closest the security industry has to a rock star,” Bruce Schneier is a world-renowned security professional, critic and commentator. It’s no wonder that his blog, Schneier on Security, is this high up on our list.
Schneier has authored dozens of books, most notably “Applied Cryptography” in 1994 (which made him a legend in the world of cryptography), “Beyond Fear: Thinking Sensibly About Security in an Uncertain World” in 2003 and his latest, “Security and Survival in a Hyper-connected World.”
He’s been running his newsletter “Crypto-Gram” since 1994 and his blog Schneier on Security since 2004. Widely known as an unapologetic security critic, Schneier was highly active during the post-9/11 TSA era, when he harshly critiqued the state of panic created by the TSA, calling the entire ordeal “security theater.”
Schneier posts on his website almost daily, and on it you’ll find cybersecurity news along with his commentary, essays, academic papers, calendar of future speaking engagements on top cybersecurity conferences (RSA 2021!) and more.
His insightful views on the value of privacy and academic approach to security with a dash of creative storytelling make Schneier on Security a blog you need in your bookmarks. It’s definitely in ours!
Favorite reads from Schneier on Security:
- In Praise of Security Theater
- Police Surveillance Tools from Special Services Group
- Hacking McDonald’s for Free Food
3. Daniel Miessler
Daniel Miessler’s field of study, interests, and topics on his blog can best be described with three words: Security, technology, and people.
Miessler has over 20 years of experience in infosec. During his long career he’s written many articles with topics including information security, OSINT, tech tutorials, philosophical pieces, learning and creativity. He currently works at the OWASP Internet of Things Security Project and runs an amazing weekly newsletter covering the best books, podcasts and blogs in the infosec industry.
We love Miessler’s blog as it covers so many topics that intersect while dealing with security from both sides: the technological, and the human. A respected thought leader in the industry, he’s provided valuable insights and critiques on different theories, such as his piece on security by obscurity which we particularly liked.
Dividing his blog content into four categories— Infosec, Technology, Philosophy and Creativity—Miessler enriches each post with its respective principle. By venturing past the infosec/tech side of each blog, Miessler engages readers with thought-provoking, philosophical writing that deals with business as much as everyday life.
Enjoy his blog, his amazing newsletter (our recommendation), or plug in to his podcast, Unsupervised Learning, if you’d like to take in his newsletter in a different form. Whichever you choose, Daniel Miessler’s website and blog are among the best in cybersecurity to follow in 2021.
SecurityTrails highly recommends these picks from Daniel Miessler’s blog:
- Secrecy (Obscurity) is a Valid Security Layer
- Be Worthy of a Wikipedia Entry
- Purple Team Pentests Mean You’re Failing at Red and Blue
4. Zero Day | ZDNet

5. Troy Hunt
Here’s another entry from our list of cybersecurity legends. Australian security expert Troy Hunt is a Microsoft Regional Director who’s also been named Microsoft’s Most Valued Professional (MVP) in Developer Security. He’s often seen in the press covering big data leaks, and in the Congress testifying on their global impact.
“Have I Been Pwned” is a project that has given Hunt worldwide recognition: the site is a public service that helps those affected with data breaches find out which of their accounts have been compromised. Besides running “Have I Been Pwned’” Troy also writes in his blog regularly, giving weekly updates on where he talks about new technology, information about his work, conferences he’s participated in and news about private workshops, analysis of data breaches, his own security experiences, and more.
Along with his blog, his website also features links to his numerous Pluralsight courses, media coverage and appearances at industry conferences and workshops. Practically a household name, it’s no surprise he’s earned his own high spot on this list.

Wired is a long-standing online publication that reports on technology and security and their impact on global politics, culture and society.
Notable about Wired is that while they might not publish a few times a day and cover every news and data breach that’s happened, they do take on topics involving security, emerging threats and cybercrime, adding insightful commentary with their recognised sense of humour and sarcasm. Some of the categories you can enjoy on Wired include business, culture, gear, transportation, security and AI.
Another thing unique about Wired is that they aren’t specifically geared towards people in the IT or security industry, but to anyone interested in learning today’s technology and its societal and cultural value. And they always include amazing graphics with each post!
Thanks to its long history and important role in the industry, Wired is a must among cybersecurity blogs. Something to keep in mind is that when you reach your daily limit of blog posts on Wired, you’ll get blocked by a big pop-up telling you to get the yearly subscription. Know that going in.
