Threat Intelligence

The attacker is no longer human.

AI has scaled the attack: scanning, phishing and vulnerability hunting now move at automation speed, not human speed. A static rule list falls behind; a firewall now needs live intelligence.

Most vendors buy ready-made intelligence lists. We produce our own: the honeypot network I operate catches attackers in real time, and this data exists on no other list. This unique intelligence feeds SiberKale projects and the customer defenses I build; full IoC data and attacker analysis are offered through Tellal package subscription. Real protection, not paperwork.

Approach

Speaks across layers.

Network, security, and software aren't separate. Think them together, get better solutions.

Method

Learned in the field, applied at the desk.

Every solution was born from a real need.

Location

Remote-ready, on-site in Marmara region.

Local intervention + remote management combined.
