Network Security Consulting
Network Architecture: From Resilience to Detection
The traditional "castle and moat" approach to network security, focusing only on perimeter defense, is no longer sufficient. Modern threats require a strategy based on deep segmentation and full visibility of internal traffic. At ExColo, we design networks that do not just block attacks but actively limit their impact through resource isolation.
Segmentation Strategy
We divide the network into logical security zones, allowing for:
- Critical Resource Isolation: Separating databases and production systems from user zones.
- Micro-segmentation: Controlling security at the individual workload level.
- DMZ Management: Safely exposing services to the outside world while maintaining strict control.
East-West Traffic Control
Most data center traffic is internal. We secure it through:
- Lateral Movement Prevention: Preventing attackers from moving freely between servers.
- Internal Traffic Inspection: Using IPS/IDS systems to detect anomalies within the network.
- Zero Trust Policies: Default denial of all communication that is not explicitly allowed.
Firewall Architecture (NGFW)
We design and optimize Next-Generation Firewall (NGFW) systems, integrating them with your identity infrastructure. This ensures access rules are based on specific users and applications (App-ID, User-ID) rather than just IP addresses.
"An effective firewall is not just a device; it is a finely tuned gateway that understands the business context of your network traffic."
Visibility and Risk Reduction
You cannot protect what you cannot see. Our solutions provide:
- Full network flow analytics (NetFlow/IPFIX).
- Identification of unauthorized devices (Shadow IT).
- Automated compliance reporting for security standards.
