Network & Infrastructure Security

Network Architecture & Management (SDN, SD-WAN, NFV)

Modern IT environments need flexible and centrally manageable networks that adapt to cloud use, remote work, and complex application landscapes. Classical network designs are too static and hard to scale.

Central control of network behavior through software
Dynamic routing and load balancing
Cost-efficient WAN operation
Virtualized firewalls, routers, and load balancers
Cloud-ready hybrid network setups

This approach uses software-based control (SDN), intelligent WAN routing (SD-WAN), and virtual network functions (NFV) to simplify and automate network operations.

Secure Access Service Edge (SASE)

With users, data, and apps everywhere, it’s no longer enough to secure just the corporate perimeter. Organizations need consistent and secure access from anywhere.

Combines networking and security functions in one service
User- and device-aware access policies
Real-time filtering of cloud and internet traffic
Reduces latency by inspecting traffic at the edge
Enables secure remote and hybrid work

SASE delivers security and performance in one unified cloud service that adapts to user identity and location.

Firewall Management (NGFW)

As threats become more complex and network boundaries blur, basic port-based filtering is no longer enough. Modern firewalls must understand what applications and users are doing.

Inspects traffic beyond ports and protocols
Blocks malicious content at the application level
Integrates with threat intelligence services
Automatically enforces central policies across locations
Helps detect lateral movement inside the network

Next-generation firewalls (NGFWs) provide deep inspection and precise control over network traffic with user and application awareness.

Intrusion Detection & Prevention Systems (IDPS)

Most traditional tools can’t detect attacks that happen inside the network or between trusted systems. IDPS helps to uncover hidden threats in real time.

Analyzes traffic for known attack patterns and anomalies
Sends alerts or blocks malicious activity instantly
Helps detect unauthorized access and malware
Works together with SIEM or SOAR platforms
Supports compliance through detailed logging

These systems monitor traffic to detect and stop harmful actions before they cause damage.

DDoS Protection

Downtime from DDoS attacks can cripple business operations. Many companies only act after their services are unavailable — which is too late.

Recognizes abnormal spikes in traffic
Filters out unwanted traffic before it reaches your servers
Protects against both volumetric and targeted attacks
Adapts defenses based on real-time behavior
Ensures service availability under attack

This service shields your infrastructure from being overwhelmed by attackers trying to exhaust your bandwidth or systems.

Network Access Control (NAC)

When unmanaged devices, guests, or contractors connect to your network, they often bypass standard protections. NAC ensures they don’t introduce risk.

Identifies and classifies all connected devices
Applies dynamic access rules based on user and device
Denies access to outdated or non-compliant systems
Offers secure onboarding for guests
Connects with directory services for access policies

NAC systems make sure only trusted and secure devices are allowed to access internal resources.

Zero Trust Network Access (ZTNA)

In a world without reliable network borders, trusting internal users or devices by default is a risk. Access should always be verified and restricted.

Requires identity checks for every access attempt
Verifies device health and context
Limits access to only necessary apps or data
Encrypts connections regardless of location
Continuously re-evaluates access during sessions

ZTNA limits exposure by enforcing identity- and context-based access instead of trusting users based on network location.

Deception Technology

Most attackers spend time moving quietly within networks. Traditional tools often miss these steps. Deception reveals them early.

Deploys fake data or systems to lure attackers
Detects unauthorized behavior quickly
Gathers intelligence about attacker methods
Supports forensic analysis with clean event trails
Runs silently without affecting real systems

This method uses decoy systems and fake data to trick and detect attackers who are already inside.

Network Analysis & Forensics

When performance drops or a breach is suspected, IT teams need a clear view of what happened — not just logs. Deep traffic insights are essential.

Captures and reconstructs full network traffic
Provides historical data for investigation
Helps identify root causes of incidents
Visualizes traffic flows and anomalies
Integrates with SIEM and IR workflows

Network forensics tools analyze past and live traffic to help respond to security issues and improve performance.

DNS Security

DNS is often overlooked but heavily abused by attackers. From malware control to phishing, many threats use DNS as a hidden channel.

Blocks access to known malicious domains
Detects DNS tunneling used for data theft
Prevents domain spoofing attacks
Encrypts DNS queries for privacy
Offers alerts and logs for suspicious activity

DNS security tools monitor and protect this foundational internet service to stop hidden threats before they escalate.
