Network Security
We design, implement, and manage network security solutions—next-generation firewalls, intrusion detection and prevention, and network segmentation. From initial assessment through ongoing operations, we handle as much or as little as you need.
Schedule Consultation ⟶View Solutions ↴Solutions
We evaluate your environment and recommend the right combination of technologies based on your architecture, threat model, and operational capacity—not vendor relationships.
NGFW
Application-aware firewall with deep packet inspection, encrypted traffic analysis, and integrated threat intelligence. We handle vendor selection, architecture, and policy development.
IDS/IPS
Network-based detection of exploits, malware, and suspicious traffic patterns. We deploy, tune, and maintain detection rules to reduce noise and improve signal quality.
SEGMENTATION
Limit lateral movement and contain potential breaches by dividing networks into security zones. We design segmentation strategies aligned with your business and compliance requirements.
NGFW Capabilities
NGFW capabilities vary by platform. We configure these features based on your environment and continuously tune for your traffic patterns.
Identify and control applications regardless of port or evasion technique. Policy tuning based on your business applications.
Map traffic to users via directory integration. Enable user-aware policies and improve investigation context.
Configure SSL/TLS inspection with appropriate bypass policies for privacy-sensitive categories and certificate handling.
Tune IPS signatures, anti-malware, and threat intelligence feeds for your environment to reduce false positives.
Implement web access policies by category. Block known malicious sites and enforce acceptable use policies.
Detect DNS-based threats including command and control callbacks and data exfiltration attempts.
Integrate cloud sandbox analysis for unknown files. Configure submission policies and response actions.
Configure comprehensive logging and integrate with your SIEM for centralized visibility and correlation.
IDS vs IPS
We help you determine the right deployment mode based on your risk tolerance, environment complexity, and operational maturity.
Deployment
Out-of-band via TAP or SPAN
Inline—all traffic flows through
Response
Alert only—requires human action
Can block traffic automatically
Risk of disruption
None—passive monitoring
Potential for false positive blocking
Tuning requirement
Lower—investigation burden only
Higher—must minimize false positives before blocking
Typical use case
Initial deployment, visibility, forensics
Mature environments with tuned rule sets
Threat Coverage
No solution detects everything. Network security provides visibility into these threat categories when properly deployed and tuned.
Known vulnerability exploitation targeting network services. Detection depends on signature currency and traffic visibility.
Malicious payloads delivered over the network. Effectiveness varies based on encryption and evasion techniques.
Outbound communications to attacker infrastructure. Detection requires threat intelligence and behavioral analysis.
East-west traffic as attackers move through the network. Requires internal visibility and segmentation.
Large or anomalous outbound data transfers. Detection limited by encryption and traffic patterns.
Malformed packets and non-standard protocol usage that may indicate attack activity or misconfiguration.
Port scanning and service enumeration. Often high-volume—requires tuning to surface meaningful activity.
Unauthorized applications, protocols, or access patterns that violate security policy.
Deployment
Deployment options we support
Physical appliances for data centers and high-throughput environments
VM-based deployment for private cloud and virtualized infrastructure
Native firewall services in AWS, Azure, and GCP environments
Firewall as a Service for distributed and remote workforce
Our Approach
How we deliver network security
We analyze your current network architecture, traffic patterns, existing controls, and gaps before recommending solutions.
We design the target architecture and evaluate vendors based on your requirements—not our partnerships or margins.
We deploy, configure, and tune until the solution is producing actionable signal with acceptable noise levels.
We provide ongoing management, monitoring, and optimization—or train your team and hand off operations.
Why intSignal
We're a security consultancy that does the work—not a reseller that hands you a box and walks away.
We recommend platforms based on your environment and requirements. We work with leading vendors and our own in-house solutions—choosing what fits, not what pays us more.
We don't disappear after implementation. We stay engaged through tuning, optimization, and ongoing operations for as long as you need us.
Our team has operated these technologies in production environments. We know what works in practice—not just vendor documentation.
Our Services
What we deliver
We evaluate your current network security posture and identify gaps in visibility, detection, and policy enforcement.
We design, deploy, and configure network security solutions—including migrations from legacy platforms with minimal disruption.
We operate your network security infrastructure—monitoring, tuning, and responding—so your team can focus on higher-value work.
Schedule a call to discuss your environment, challenges, and how we can help—whether that's a targeted assessment or full managed services.
No obligation. We'll provide honest guidance even if we're not the right fit.
