An all-encompassing data security package that features Zero Trust Network Access (ZTNA), two-factor authentication (2FA), and privileged access management (PAM) is now available. Additionally, it incorporates SQL firewalls and data access management (DAM) to bolster protection. This solution is designed to safeguard companies against data breaches and cyber threats. Furthermore, it assists organizations in adhering to compliance standards and fulfilling cyber insurance obligations, ultimately enhancing their overall security posture.

OpenVPN Access Server is a self-hosted Zero Trust Network Access (ZTNA) solution that runs inside your own environment — on-prem or your AWS, Azure, or GCP account — keeping tunnel traffic and configuration off any third-party network. Access is scoped to the application, not the IP or subnet: each user is routed only to the specific app they're authorized for, identified by domain name, with nothing else on the network visible to them. That makes lateral movement structurally impossible, not just restricted by policy. Access Server Link turns setup into a guided flow (hostname, cloud, region, password), with SSL certificates provisioned and renewed automatically, eliminating manual certificate handling as a source of risk. Because entitlements are bound to hostname rather than IP, they hold up through IP changes and autoscaling with no manual rework. Your instance remains entirely under your control, giving you the data ownership and audit trail needed for HIPAA, SOC 2, and GDPR — full control of the stack, delivered with SaaS-level ease. Administration happens through a browser-based portal instead of SSH: users, certificates, and access rules are managed without shell access, narrowing your attack surface. The Zero Trust App Broker routes each connection through a placeholder IP tied to a single authorized app — the real destination stays hidden, so a stolen credential offers no way to scan or reach other systems. Least privilege is built into the architecture, not left to policy that can drift. Native clients cover Windows, macOS, iOS, Android, and Linux, keeping identity- and app-based controls consistent across every endpoint. Templated deployment on AWS, Azure, and GCP means security teams get standardized, auditable rollouts rather than one-off manual builds.

Organizations moving away from legacy VPN appliances toward zero-trust security can turn to CloudConnexa, OpenVPN's fully managed, cloud-native platform combining Zero Trust Network Access (ZTNA) with Security Service Edge (SSE) functionality. Instead of standing up their own servers, customers get an on-demand private overlay network, effectively a distributed router paired with a next-gen firewall running in the cloud, built across a full-mesh backbone of 30+ regions worldwide that keeps latency low and connections resilient. To bring private resources into that network, admins deploy Connectors: a Network Connector links an entire site (an office, data center, or an AWS/Azure virtual network), while a Host Connector plugs in a single machine or IoT device. Each connected Host runs OpenVPN client software to publish its services. All traffic, whether from remote employees, branch sites, or cloud workloads, travels through encrypted OpenVPN tunnels, and Linux endpoints can enable Data Channel Offload (DCO) to push more throughput. Who can reach what is controlled through role- and group-based policy tied to identity, backed by SAML, LDAP, and SCIM connections to existing directories, so access stays scoped to exactly what each user needs. Routing by application domain hides the true IP of backend servers, delivering microsegmentation without revealing infrastructure. Security is rounded out by the Cyber Shield suite: DNS-based filtering across 40+ threat categories, IDS/IPS protection, device posture enforcement (DIVE), and two-factor login. Logging, SIEM export, and alerting give admins the audit trail they need, and every setting lives inside one cloud console.

Pomerium offers a secure, clientless solution that enables users to easily access web applications and services without needing a corporate VPN. Its emphasis on improving developer productivity eliminates complicated access procedures that could hinder workflow efficiency. In contrast to traditional client-based tunneling solutions, Pomerium provides fast connections with low latency while upholding strong security and privacy measures. By using contextual information for access control, it embraces a principle of continuous verification, exemplifying a zero trust framework where each action is evaluated based on contextual factors before being approved or denied. This approach differs significantly from NextGen VPNs, which generally only verify authentication and authorization at the start of a session. Additionally, Pomerium allows secure access to a wide range of platforms, including web applications, databases, Kubernetes clusters, internal tools, and legacy systems, making it a versatile option for individuals as well as teams of various sizes. Through its innovative methodology, Pomerium is transforming how organizations oversee access to their digital assets while enhancing overall security protocols.

LayerV is a specialized access framework that caters to both individuals and AI systems, enabling organizations to provide regulated entry to internal web applications, APIs, and back-end infrastructures while effectively shielding the origin of these applications from direct public exposure. By placing a connector next to a private resource, organizations can ensure that access is granted strictly according to their own authentication processes and policy regulations. This innovative system empowers teams to share temporary access, control which users or entities can engage with a resource, and withdraw permissions as necessary. Specifically designed for developers, IT experts, and security personnel who oversee systems with demanding access requirements for employees, contractors, and software agents, LayerV is versatile enough to protect internal tools and APIs, facilitate temporary access to private assets, and enable AI agents to interact with authorized systems without compromising their confidentiality. In addition to enhancing security, LayerV also simplifies the management of access to sensitive resources, making it an invaluable tool for organizations navigating the complexities of modern digital environments. Ultimately, its implementation can lead to improved efficiency and a more structured approach to access control, reinforcing the organization's commitment to security and compliance.

To safeguard against data loss, malware, and phishing attacks, implementing a high-performance Zero Trust application access and internet browsing solution is essential. Relying solely on traditional tools to connect employees to corporate systems often leads to excessive trust being granted, creating significant data risks. The complexity of managing the corporate perimeter has escalated due to inconsistent configurations among VPNs, firewalls, proxies, and identity providers. Additionally, deciphering logs and comprehending user access to sensitive data has become increasingly intricate in today’s environment. It is vital for employees, partners, and customers to have access to a network that is secure, fast, and reliable for their operations. By adopting Cloudflare Zero Trust, traditional security barriers are replaced with a vast global edge, which boosts both speed and security for teams around the globe. This method guarantees that consistent access controls are enforced across cloud-based, on-premise, and SaaS applications, thereby facilitating a smooth and secure user experience. As cybersecurity threats continue to evolve, it is imperative to stay proactive and adaptive in order to ensure ongoing and effective protection against new challenges that may arise. Regular assessments and updates to security strategies will further enhance your organization’s resilience against these ever-changing threats.
