Cybersecurity is one of the busiest topics on LinkedIn: we count 13,637 cybersecurity posts in the last 12 months in our dataset alone. Almost all of them sink. The typical cybersecurity post earns 25 likes.
So who actually moves the needle when they talk about security? At MagicPost, we took the 141 creators in our dataset who post about cybersecurity consistently (at least 10 cybersecurity posts in the last 12 months, minimum 5,000 followers) and ranked them by median likes on their cybersecurity posts alone. Not their overall fame: what happens, today, when they hit publish on this specific topic. Number twenty earns more than 6 times the typical cybersecurity post. Number one earns 41 times it.
Two numbers you will not find anywhere else sit in each profile below: the share of feed (is security their life or a guest appearance?) and the vs-overall figure: whether their cybersecurity posts earn more or less than their own usual median. For several of these 20, security is where the audience came from; for others, it is the rare post that quietly outperforms everything else.
The full board first, then the countdown:

TL;DR: We ranked the top 20 LinkedIn creators on Cybersecurity by one number nobody else publishes: median likes on their cybersecurity posts alone, over 12 months and 141 creators. Neo Kim leads with 1,027 median likes per cybersecurity post, 41x what the typical cybersecurity post earns (25 likes).

298k | 1,027 | 10 | 3% | -5% | 0.34% |
Neo Kim tops this ranking, and he does it as a system-design educator, not a security specialist. His median cybersecurity post earns 1,027 likes, 1.8 times the #2 and 41 times the typical cybersecurity post on LinkedIn. The twist is in his focus: cybersecurity is only 3% of his feed, the lowest share of the top 20, and those posts sit close to his (already very high) overall median. His yearly cybersecurity median rose from 689 in 2025. His best post is a practitioner checklist.
"If I wanted to build a secure API, I'd consider these 12 practices." His most liked cybersecurity post of the year: 1,710 likes. Read it
Where do these cards come from? Every figure on this page runs on MagicPost's LinkedIn analytics: median engagement per theme, share of feed, theme premiums, trajectories, across 141 cybersecurity creators and 13,637 cybersecurity posts. It works on your profile too, including a side-by-side with anyone on this list.
Just missed the cut
Five names land right behind, and they say a lot about how this ranking works. John Hammond (#21, 150 median likes per cybersecurity post) is probably the most famous "cybersecurity creator" on the platform, with a 375k audience and 69 security posts in 12 months, and he misses the cut for a structural reason: volume. A median is merciless with frequency, since every additional post has to beat your typical one. Then come Florian Burnel (#22, 143), Ross Haleliuk (#23, 134), Inga S. (#24, 131) and Laurent Biagiotti (#25, 131). Publish a little less, hit a little harder, and any of the five enters the top 20 at the next quarterly refresh.
The efficiency champions (pound for pound)
Raw likes favor big audiences, so here is the other cut: engagement rate on cybersecurity posts, median likes divided by followers (minimum 20k followers). The list changes completely:
Creator | Followers | Engagement rate | Median likes (cybersecurity) |
39k | 0.80% | 314 | |
80k | 0.71% | 566 | |
20k | 0.65% | 131 | |
66k | 0.49% | 327 | |
27k | 0.48% | 131 |
The champion is Rinki Sethi: a 0.80% engagement rate on 39k followers, just ahead of saed, who holds a 0.71% rate on an audience twice the size. Sethi, saed and Marcus Hutchins are the three names in both the absolute top 20 and this efficiency top 5.
The volume game (total cybersecurity engagement)
One more cut: not the typical post, but the total likes generated on cybersecurity posts over 12 months. This is where the high-frequency voices get their due:
Creator | Total likes on cybersecurity (12 mo) | Cybersecurity posts |
85,822 | 107 | |
62,620 | 139 | |
39,482 | 198 | |
29,430 | 161 | |
25,663 | 117 | |
18,714 | 265 | |
16,464 | 89 | |
16,458 | 114 |
saed generates the most total engagement with 107 posts; Chirag Goswami needs 198 to reach roughly half of it. This is also the cut where the steady daily voices belong: Karan Dwivedi clears 18,000 total likes one post at a time, across 265 of them.
The conversation champion
The ratio of comments to likes, the cut nobody publishes. The cybersecurity record belongs to Inga S.: a 0.40 comment-to-like ratio on her security posts, against a platform norm closer to one comment per ten likes. A security and risk leader, she turns her feed into a discussion rather than a broadcast, on a 73% security focus.
The residents and the tourists
Of the 141 creators who post cybersecurity consistently, only 59 dedicate more than half their feed to it. This top 20 splits the same way: residents like Dija S (85% of her feed), Yasmine Douadi (81%) and Jen Easterly (72%), and tourists like Neo Kim (3%) and Sol Rashidi (5%) whose rare security posts ride on a much larger general audience.
The data behind that tourist effect is consistent: an audience that did not sign up for security still rewards a clear, useful security post, while full-time security feeds compete with themselves. Several of this top 20 earn a premium of 50% or more on security, and they keep it well under a fifth of what they publish. If you write about cybersecurity occasionally, you are playing the easier game.
Two related studies while you are here: who dominates LinkedIn country by country (the United States, France, Germany, India, the full series), and the rest of the theme rankings on the creators pillar. And if your plan includes showing up in these creators' comments, an engagement feed makes that a daily five-minute habit.
Study them, then study yourself. With MagicPost you can analyze any cybersecurity creator the way we just did (median engagement by theme, share of feed, premiums, trajectory) and benchmark your own profile. The data on this page is the product.
Where this data comes from
Everything in this article is MagicPost's own research, not a copied list. MagicPost analyzed 13,637 cybersecurity-themed LinkedIn posts from the last 12 months, kept the 141 creators with at least 10 cybersecurity posts and 5,000 followers (deleted posts excluded, company pages excluded), and ranked them by median likes on their cybersecurity posts. This is the smallest qualifying pool of the theme series, so a strong run of posts moves a creator further here than in busier themes. We also computed each creator's share of feed, their cybersecurity premium versus their own overall median, engagement rates and conversation ratios. Rankings refresh as the data does; figures dated June 2026. No one paid to be on this list, and no one can: it is arithmetic.
SSS
Who is the top cybersecurity creator on LinkedIn in 2026?
By real impact (median likes on cybersecurity posts over the last 12 months), Neo Kim: 1,027 median likes per cybersecurity post, 1.8 times the number two (saed) and 41 times the typical cybersecurity post on LinkedIn.
How is this ranking calculated?
Median likes on each creator's cybersecurity-themed posts over the last 12 months, among the 141 creators MagicPost analyzes with at least 10 cybersecurity posts and 5,000 followers. Median, not average, so one viral post cannot buy a spot, and only cybersecurity posts count, so general fame cannot either.
Does posting about cybersecurity boost engagement on LinkedIn?
For many of this top 20, yes: premiums run as high as 137% (Mohamed Hamdi Ouardi) and 96% (Marcus Hutchins). The effect is strongest for "tourists" whose feed is mostly about something else. But the typical cybersecurity post still earns just 25 likes: the topic rewards clarity, not participation.
Who are the most efficient cybersecurity creators?
By engagement rate on cybersecurity posts (median likes / followers, minimum 20k followers): Rinki Sethi of Upwind Security (0.80%), just ahead of saed of Google (0.71%), Laurent Biagiotti (0.65%) and Marcus Hutchins (0.49%).
Are the top cybersecurity voices full-time security creators?
Mostly mixed. Only 59 of the 141 eligible creators dedicate more than half their feed to security, and the top 20 ranges from full-time residents (Dija S, Yasmine Douadi, Jen Easterly) to near-tourists whose security posts are a small slice of a much larger feed (Neo Kim at 3%, Sol Rashidi at 5%).
Which countries dominate cybersecurity content on LinkedIn?
The United States leads this top 20 with nine, India places four, the United Kingdom and France two each, and Germany, Brazil, Australia and Tunisia one each. Country-by-country rankings are in our country series.
