Effectively manage your remote workforce by facilitating the quick deployment of both company-owned and personal devices, along with endpoints used by contractors. Reduce the likelihood of security breaches by implementing a Zero Trust secure access framework that continuously verifies the identity of both users and devices, which in turn decreases the potential attack surface. By improving access efficiency, enhancing security, and delivering performance that surpasses traditional VPNs, you empower your staff to work more effectively. Access management is crucial to maintaining a robust security posture. The CloudGen Access Zero Trust framework provides exceptional control over user and device access while mitigating the performance issues often seen with conventional VPN solutions. It enables remote, conditional, and contextual access to essential resources while also limiting excessive privileges and the associated risks from third-party engagements. Additionally, CloudGen Access ensures that employees and partners can access corporate applications and cloud resources without introducing new vulnerabilities. This all-encompassing approach not only safeguards your infrastructure but also allows security protocols to adapt to the evolving demands of remote work environments, ensuring that your organization remains resilient in the face of emerging threats.

NetFoundry is an identity-first Zero Trust networking platform built to secure workload connectivity across applications, APIs, cloud infrastructure, data centers, AI agents, industrial systems, and distributed sites. The platform is based on OpenZiti, the open source Zero Trust networking technology created and maintained by NetFoundry. Rather than connecting systems primarily by IP address, NetFoundry assigns cryptographic identities to workloads and uses policy to determine which identities can communicate with specific services. Authorized sessions are established through outbound-only, end-to-end encrypted connections, leaving protected services without inbound ports that can be scanned or directly attacked. This architecture can reduce reliance on traditional VPNs, firewall rules, network address translation, static routes, and IP allowlists when connecting distributed workloads. Identity-based microsegmentation allows teams to create least-privilege paths between individual services and helps limit lateral movement if one system is compromised. Site-to-site capabilities connect clouds, branches, plants, partner networks, and other environments without requiring conventional tunnel management or unique IP address ranges. NetFoundry also provides controls for AI agents so organizations can govern machine-to-machine access, apply consistent policies, and track interactions across AI infrastructure. API security capabilities can keep services unreachable until authentication and authorization are complete, while OT and IoT features help secure legacy or sensitive environments without modifying individual controllers. Software vendors and solution providers can embed NetFoundry connectivity into their own products to reach customer environments without requiring customers to expose inbound ports or configure traditional VPN access.

As remote work continues to expand, security teams face increasing difficulties due to diminished visibility and control over devices accessing their networks, as well as their security configurations. This challenge is exacerbated by the requirement for various point solutions to ensure proper monitoring and management. MetaAccess addresses these concerns by delivering secure network access alongside comprehensive endpoint compliance within a single, integrated platform. This cohesive strategy not only simplifies ongoing management processes but also reduces time and effort, significantly lowering overall risk. Cybersecurity threats, such as Advanced Persistent Threats and Distributed Denial of Service (DDoS) attacks, represent major threats, particularly for remote workers, which underscores the urgent need for more effective solutions beyond traditional VPNs. The Software Defined Perimeter (SDP) strengthens security measures while sidestepping the typical costs and performance issues tied to VPNs, thus providing an enhanced user experience that aligns with the expectations of today’s remote workforce. By implementing SDP, organizations can better protect their networks while also embracing the adaptability necessary in contemporary work settings, ultimately ensuring a secure and efficient operational environment.

Verizon's Software Defined Perimeter (SDP) represents a Zero Trust approach to networking, prioritizing secure remote access, internal systems, and cloud applications. This robust solution is engineered to protect against network threats from unauthorized users and devices. One of the primary obstacles for CIOs currently is the challenge of integrating various cloud services, as many companies utilize multiple cloud providers. Although this multi-cloud strategy offers increased flexibility, it can often necessitate data rerouting, which in turn may lead to reduced performance and higher latency for users. Moreover, the trend of remote work has resulted in more employees and contractors working from home, further complicating access to secure networks. Verizon’s SDP effectively tackles these challenges by establishing a secure environment that safeguards enterprise and cloud applications from external threats while allowing authorized users to efficiently access the necessary applications on their designated devices. This not only enhances productivity and security but also ensures that sensitive data remains protected across multiple platforms. Ultimately, Verizon’s SDP is a vital tool for organizations aiming to maintain security and operational efficiency in an increasingly complex digital landscape.
