What network security solution best meets Company XYZ's requirements for integrating networks and services with Company ABC?

Choosing to place a Company ABC managed firewall in Company XYZ's hub site is a strategic move that directly addresses the challenge of integrating networks and services securely. This option allows for centralized control over the traffic that flows between the two companies, ensuring that security policies established by Company ABC are enforced effectively.

By managing the firewall, Company ABC can implement tailored security measures suited to its specific needs while ensuring that any data exchanged between the two companies is protected from unauthorized access or threats. This setup not only provides a robust defense against potential security breaches but also facilitates compliance with both companies' security policies and standards.

Additionally, this solution avoids the complexities and potential vulnerabilities associated with merging networks or simply relying on a VPN, which could introduce risks if not configured correctly. A well-managed firewall also allows for ongoing monitoring and technical support, enabling both companies to adapt to evolving security threats as they arise. The use of a managed firewall consolidates security measures, creating a clear boundary between the two entities while allowing them to communicate and share services securely.
