Endpoint, network, email and web are four doors an attacker passes in turn. Sanal Çekirdek treats them as layers of one defense architecture rather than four separate products.
When every layer has its own console, none of them knows what the others saw. That information gap is exactly where an attacker moves.
Signature-based blocking is not sufficient on the endpoint; behavioral detection and remote response capability are required. Isolating a device, stopping a process and collecting evidence should all be possible from one interface.
On a flat network, one compromised device reaches everywhere. Segmentation raises the cost of lateral movement; traffic between segments opens only in the required direction and on the required ports.
Most attacks still begin with email. Authentication records, attachment and link analysis, external sender marking and a user reporting path are built together — and a report must land in an analysis queue.
Web access and the layer in front of the application must share the same identity and the same event stream as the other three. Coherence comes from events converging in one place, not from products sharing a brand.
What decides is not the brand but whether events can converge. A single vendor makes coherence easier; if different products are chosen, integration capability has to be a purchasing criterion.
It is necessary against known malware but not sufficient. Attacks that abuse legitimate tooling leave no signature, which is why behavioral detection and response capability matter.
It runs in stages. The management network and critical systems are separated first; full segmentation widens step by step as application dependencies are mapped.
Let's establish what your four layers cover today and close the gaps between them together.
