The Challenge: Secure Remote Connectivity for a Financial Company

A financial company with over 500 employees needed to enable remote work without compromising the security of its critical data. The existing infrastructure lacked a robust corporate VPN, and the firewalls were not optimized for modern threats. At ForgeNEX, we designed a comprehensive solution combining secure VPNs and next-generation firewalls, following industry best practices.

Phase 1: Risk Assessment and Architecture Design

We conducted a vulnerability analysis and penetration test, similar to what we describe in our article on Ethical Hacking and Penetration Testing for Companies. This allowed us to identify gaps in network segmentation and access policies. We designed an architecture with VPN tunnels based on IPsec and SSL/TLS, multi-factor authentication (MFA), and firewalls with deep packet inspection (DPI).

Phase 2: Implementation of Secure VPNs

We deployed a remote access VPN solution using standard protocols such as IKEv2 and OpenVPN, with AES-256 encryption. Each employee received a unique digital certificate and was integrated with the active directory for permission management. Additionally, we implemented a site-to-site VPN tunnel to connect the headquarters with branches, ensuring all traffic was encrypted.

Phase 3: Configuration of Next-Generation Firewalls

We installed firewalls with intrusion prevention system (IPS) capabilities, content filtering, and application control. We configured access rules based on the principle of least privilege and segmented the network into zones: internal, DMZ, and remote access. This allowed isolating critical systems and monitoring traffic in real time.

Phase 4: Testing and Validation

We conducted stress tests and simulated attack scenarios to verify the effectiveness of the configuration. We used continuous monitoring tools to detect anomalies, an approach we also recommend in our guide on Observability for Processes and Automations.

Results and Conclusions

The company achieved a 95% reduction in security incidents related to unauthorized access. Employees were able to work remotely with the same security as in the office. This case demonstrates that a proper secure VPN and firewall configuration is key to digital transformation, especially in regulated sectors like finance.
