Case Study: Advancing Network Security Resilience
How a Managed Network Services Provider Improved Visibility, Reduced Risk Exposure, and Cut Cyber Insurance Premiums by 59%
Industry Example: Network Security / Managed Network Services Provider (MSP)
Company Size: ~350 employees across 3 global operations centers
Annual Revenue: US $190 million
Estimated Cyber Insurance Premium (Before): US $670,000/year
Estimated Cyber Insurance Premium (After): US $275,000/year
Savings: ~59% reduction through validated cyber controls and real-time monitoring
The Challenge
A leading Managed Network Services Provider (MSP) delivering enterprise-grade firewalls, SD-WAN, and security infrastructure to clients worldwide recognized a growing challenge: the company itself had become a prime target.
As cybercriminals increasingly exploited MSPs and network providers as gateways to their clients’ environments, the organization faced increasing scrutiny from both insurers and customers.
Despite maintaining strong technical controls, the firm struggled with:
Limited visibility into the security health of internal management networks and customer environments
Lack of continuous validation that firewall rules, MFA enforcement, and segmentation policies were working as intended
Complex audit requirements for ISO 27001, SOC 2, and insurer renewals
Escalating insurance premiums driven by the perceived “aggregated risk” of client network exposure
To retain client confidence and maintain competitive margins, leadership sought a way to quantify and continuously prove its cyber resilience to insurers and enterprise customers alike.
The Solution
The provider implemented a continuous cyber assurance and control validation platform (based on the Antigen Security approach) to monitor, verify, and document the effectiveness of its network and security controls in real time.
Key components included:
Automated Control Validation: Continuous verification of firewall configurations, network segmentation, endpoint protection, and MFA enforcement across all management and client-access environments.
Live Threat & Exposure Mapping: Identification of misconfigurations, open ports, and policy drift across client networks managed by the MSP.
Risk-Based Compliance Reporting: Generation of audit-ready documentation mapped to ISO 27001, SOC 2, and NIST Cybersecurity Framework requirements.
Insurer-Focused Risk Scoring: Clear, data-driven cyber maturity reports aligned with insurer underwriting frameworks.
Incident Readiness & Simulation: Scenario-based tabletop exercises simulating client-impacting ransomware and supply chain attacks.
The Outcome
Within 45 days, the implementation uncovered:
37 outdated VPN configurations with weak authentication policies
Three legacy firewalls still allowing management interface access from public IP ranges
Policy inconsistencies across client segmentation rules leading to potential lateral movement exposure
Remediation was prioritized and validated automatically.
Quantifiable Results:
Cyber control compliance improved from 74% to 98% across global operations centers
59% reduction in annual insurance premiums and improved coverage terms
$395,000 in annual premium savings reinvested into further automation initiatives
Improved cyber maturity rating from “moderate risk” to “low risk” per insurer assessment
No client-impacting security incidents in the following 12 months
Operational Gains:
80% faster compliance documentation process for ISO and SOC audits
45% reduction in manual network policy reviews
Increased insurer and client confidence, leading to faster contract renewals and higher win rates in competitive bids
Why It Matters for the Network Security Industry
Network security and managed service providers are the frontline of cyber defense—but they’re also high-value targets. A single misconfiguration can cascade across dozens of client networks, leading to data loss, service disruption, and major reputational damage.
Key challenges include:
Constantly changing configurations across multi-tenant environments
Growing complexity of regulatory and insurer demands
Balancing service agility with verifiable security assurance
Continuous validation and insurer-ready reporting enable network security providers to:
✅ Demonstrate verified security maturity to clients and insurers
✅ Reduce cyber insurance costs while expanding coverage
✅ Prevent policy drift and misconfiguration risk in real time
✅ Accelerate compliance with ISO, SOC, and NIST frameworks
✅ Strengthen customer trust and brand reputation
