A comprehensive zero-trust cybersecurity transformation that achieved zero breaches over 18 months after the client had experienced 3 data breaches in the prior year.
The Challenge
ShieldNet Capital's flat network architecture and perimeter-only security had been breached 3 times in 12 months. Attackers had exploited unpatched VPN appliances, phishing campaigns targeting employees, and a misconfigured cloud storage bucket to access client financial data. The breaches resulted in $2.1M in incident response costs, regulatory fines, and client remediation. Employee security awareness was minimal, with 34% clicking phishing simulation links. No incident response plan existed.
- 3 data breaches in 12 months exposing sensitive client financial data
- $2.1M in combined incident response, regulatory fines, and client remediation costs
- Flat network architecture with no segmentation — one compromised device gave access to everything
- 34% of employees failed phishing simulations, clicking malicious links without reporting
- No SIEM, no incident response plan, and 6-month average time to detect breaches
Our Solution
Advenno implemented a comprehensive zero-trust security architecture with micro-segmentation, deployed an enterprise SIEM with 24/7 SOC monitoring, rolled out endpoint detection and response across all devices, conducted quarterly penetration testing, and established a security awareness program that transformed the human element from the weakest link to the first line of defense.
- Zero-trust architecture with identity verification, micro-segmentation, and least-privilege access controls
- SIEM deployment with correlation rules, automated threat detection, and 24/7 SOC monitoring
- EDR solution across all 450 endpoints with automated containment and forensic capabilities
- Quarterly penetration testing with red team exercises simulating advanced persistent threats
- Comprehensive security awareness program with monthly phishing simulations and gamified training
Our Approach
Security Assessment & Gap Analysis
Performed a comprehensive security assessment including network architecture review, vulnerability scanning, configuration audits, and policy gap analysis against NIST CSF and SOC 2 frameworks.
Zero-Trust Architecture Design
Designed and implemented network micro-segmentation, multi-factor authentication everywhere, conditional access policies, and encrypted communications for all internal and external traffic.
SIEM & SOC Deployment
Deployed Splunk SIEM with custom correlation rules for financial services threat patterns, integrated log sources from all 140+ systems, and established 24/7 SOC monitoring with defined escalation procedures.
Endpoint Protection & Response
Rolled out CrowdStrike EDR across all endpoints with automated containment policies, configured threat intelligence feeds, and established forensic investigation procedures.
Human Firewall Program
Launched a comprehensive security awareness program with role-based training, monthly phishing simulations with escalating difficulty, and a gamified reporting system that rewards employees for identifying threats.
The Results
ShieldNet Capital achieved zero data breaches in the 18 months following the security overhaul. Mean time to detect threats dropped from 6 months to 12 minutes with the SIEM and SOC. Employee phishing click rates fell from 34% to 4.2%, and threat reporting increased by 680%. The organization passed its SOC 2 Type II audit on the first attempt and received commendation from financial regulators for the improved security posture. Two attempted intrusions were detected and blocked within minutes.
Technologies Used
After three breaches, our board was questioning whether we could survive another one. Advenno didn't just patch holes — they rebuilt our entire security foundation. We went from fearing auditors to welcoming them.
