Introduction

In a world where cybersecurity is a priority, proper configuration of VPNs and firewalls has become a fundamental pillar for protecting companies' digital assets. In this success story, we explore how a medium-sized company managed to implement a secure network infrastructure, reducing vulnerabilities and improving the productivity of its remote team. This article belongs to the category of Network Security and is part of our series of Success Stories.

The challenge: mobility without compromising security

The company, with 150 employees and operations in three countries, needed its sales and technical support team to access internal resources from remote locations. However, the use of improperly configured VPNs and outdated firewalls had generated multiple security incidents. As we saw in our article on the alliance against exploits, protecting open source and networks is crucial in the AI era.

Solution implementation

A site-to-site VPN architecture with AES-256 encryption and multifactor authentication was chosen, combined with next-generation firewalls that integrate intrusion prevention systems (IPS). The configuration included network segmentation and role-based access policies. Below is a diagram of the implemented topology:

This case demonstrates that careful configuration of VPNs and firewalls not only protects the network but also boosts productivity. To delve deeper into the concepts, we recommend our Complete network security guide, which details the technical steps. Additionally, integration with automation tools, as mentioned in Automation and observability, can further optimize security management.

Conclusion

The combination of secure VPNs and robust firewalls is essential for any company looking to protect its data and facilitate remote work. This success story is an example of how proper planning and the use of current technologies can make a difference.
