Cybersecurity for ISPs
ISPs operate some of the most complex and exposed network environments in any industry. We harden your infrastructure, close attack surfaces, and build the processes that keep you secure under pressure.
Security Built for the ISP Attack Surface
Standard enterprise security frameworks don't map cleanly onto ISP environments. Your infrastructure spans dozens of physical sites, thousands of subscriber edge devices, public-facing infrastructure, and an operational team that needs fast access to fix things. Security controls that ignore this reality create friction without protection.
Our cybersecurity work for ISPs starts with understanding your specific topology and operational model. We identify what's exposed, what's misconfigured, and what's missing — then build a hardened baseline that your team can maintain.
What We Deliver
Infrastructure Hardening
Systematic hardening of routers, switches, and servers — disabling unused services, enforcing strong authentication, and applying vendor security baselines.
Network Segmentation
Design and implementation of management VLANs, OOB networks, and traffic segmentation that separates infrastructure from subscriber and staff planes.
Firewall Policy Review
Complete audit of existing ACLs and firewall rules — identifying contradictions, overly permissive rules, and gaps. Rewrite and documentation included.
IDS/IPS Deployment
Placement and tuning of intrusion detection sensors at key aggregation and edge points to provide visibility into anomalous traffic patterns.
DDoS Mitigation Design
Architecture recommendations for DDoS mitigation — upstream scrubbing, blackhole routing, rate-limiting, and BGP flowspec policies for volume-based attacks.
Incident Response Planning
Develop tiered IR playbooks covering detection, containment, communication, and post-incident review. Validated with tabletop exercises.
How a Security Engagement Works
Security Posture Assessment
We map your environment — network topology, exposed services, authentication controls, monitoring gaps, and existing policies.
Risk Prioritization
Findings are ranked by exploitability and impact. You get a clear priority list — critical issues addressed first.
Hardening Implementation
We implement approved changes alongside your team — firewall rewrites, VLAN redesign, OOB deployment, authentication hardening.
Validation & Documentation
Changes are verified, documented, and handed over with a security baseline document your team can maintain and audit against.
