Cybersecurity: 10 sub-niches to consider.
Adjacent to AI growth. Every new agent layer creates new attack surfaces, the security wedge follows the platform shift.
Each entry below is a specific opportunity inside Cybersecurity. We name public projects as examples, never the founders we track inside the paid product. The category commentary is the public surface; the named buyers’ edge lives in the paid product.

How Cybersecurity is tracked
The data behind the niches is the same data behind the panel.
Cybersecurity is one of the 20 top-level sectors in the weekly GitHub momentum panel. The sub-niches above are editorial slices on top of that data - specific opportunities where the signal shape suggests something is breaking out. The named scoreboard for Cybersecurity is in the startups-to-watch surface; the niche-down map here is the “what could be built” layer above it.
