Why the future of security is no longer defined by networks, but by platforms, models and public AI ecosystems.

The New Cyber Perimeter
For decades, cyber security has been built around one idea:
protect the network.
Firewalls, endpoints, VPNs, zero-trust — everything assumed that the perimeter was physical or digital infrastructure owned by the organisation.
In 2026, that assumption is no longer true.
The new perimeter is public, distributed, and AI-driven.
Where Attacks Now Begin
Modern attacks no longer start inside a corporate network.
They now begin on:
GitHub
Reddit
Telegram
Paste sites
Model hubs
AI marketplaces
Developer forums
This is where exploits are shared, refined, forked and deployed.
By the time an attack reaches your firewall, it has already been:
Tested
Optimised
Distributed
Replicated
The real risk exists outside the network.
AI Has Moved the Battlefield
AI has turned open platforms into operational infrastructure for attackers.
Instead of building malware from scratch, threat actors now:
Generate exploit code with LLMs
Share payloads via GitHub and Pastebin
Coordinate through Telegram and Discord
Use AI agents to adapt and redeploy
These platforms have become unofficial command-and-control layers.
They sit entirely outside traditional security visibility.
Why the Old Perimeter No Longer Works
Firewalls protect IP addresses.
EDR protects endpoints.
SIEM protects logs.
None of these protect:
Public code repositories
Model marketplaces
Open AI communities
Agent coordination channels
This creates a massive blind spot — exactly where modern threats now operate.
The New Perimeter Is Intelligence
In 2026, security is no longer about blocking access.
It is about seeing threats before they reach you.
The new perimeter is:
Continuous monitoring of open platforms
Detection of emerging AI misuse
Correlation across public sources
Early warning of real-world impact
This is the layer Fortaris is built for.
We monitor where AI threats are created, shared and deployed — not just where they land.
Final Thought
Security teams can no longer defend what they cannot see.
The future of cyber defence is not inside the network.
It is in the public AI ecosystem that surrounds it.
That is the new cyber perimeter.
