Seqrite ZTNA
Zero Trust Network Access (ZTNA) is a security model that grants application-specific access based on continuous identity and device verification, rather than granting broad network access once a user connects, as legacy VPNs do. This “never trust, always verify” approach authenticates every access request individually, minimizing the attack surface compared to network-centric models where a single successful login can expose an entire network.
ZTNA differs from a traditional VPN by granting precise, application-specific access rather than broad network-level access, and by verifying every access request continuously instead of trusting a user by default once connected. This distinction matters because a compromised VPN session can expose an entire network to lateral movement, while ZTNA’s application-centric model limits an attacker’s reach even if one set of credentials is compromised.
VPN’s trust-by-default model is considered a security risk because once a user authenticates, they typically gain broad access to the entire network, allowing an attacker who compromises those credentials to move laterally with minimal additional resistance. This is precisely the vulnerability Zero Trust architectures are designed to eliminate, replacing one-time authentication with continuous, per-request verification tied to specific applications rather than the whole network.
Application-centric access means users are granted access only to the specific application or resource they need, rather than to the broader network, which significantly reduces the attack surface available to a compromised account. If an attacker compromises one set of credentials under this model, they can only reach the single application those credentials were scoped to, rather than moving freely across the network as they could under a traditional VPN.
Seqrite ZTNA supports both agent-based and agentless connectivity, giving organizations flexibility to secure a wide range of devices and deployment scenarios without forcing every endpoint into the same access model. This flexibility matters for organizations with mixed environments, such as managed corporate devices alongside contractor or BYOD devices, where installing an agent isn’t always practical or possible.
Device posture assessment evaluates whether a connecting device meets security requirements, such as up-to-date patches and endpoint protection, before granting access, ensuring only compliant and trusted devices can reach enterprise applications. This real-time check happens continuously rather than just at initial login, so a device that becomes non-compliant mid-session can have its access reassessed accordingly.
User-device binding links a specific user identity to a specific device, so credentials alone aren’t sufficient to gain access the request must also come from a recognized, trusted device tied to that user. This significantly raises the bar for attackers, since stolen credentials used from an unrecognized device would be blocked even if the username and password themselves are correct.
Yes, Seqrite ZTNA supports secure access to thick-client applications like SAP, in addition to web applications and services such as RDP, SSH, and VNC, ensuring Zero Trust enforcement extends across an organization’s full application environment. This broad application support matters because many enterprises still rely heavily on legacy or thick-client systems, and a ZTNA solution limited to web apps alone would leave significant gaps in coverage.
Yes, Seqrite ZTNA includes built-in security enhancements such as a Web Application Firewall (WAF), a layer-7 firewall, and DDoS mitigation, consolidating protections that would otherwise require separate point solutions. This reduces the complexity and cost of stitching together multiple standalone security tools, giving organizations a more unified defense posture directly within the ZTNA platform itself.
ZTNA supports hybrid and remote workforces by providing seamless, application-specific access that operates in the background regardless of a user’s location, unlike VPNs, which often require manual connection and can become a performance bottleneck at scale. Because ZTNA is cloud-native and application-centric rather than network-centric, it scales more naturally with a distributed workforce than VPN infrastructure, which becomes increasingly complex to manage as remote access needs grow.
Tag-based policy enforcement uses attributes about users and applications to create dynamic, adaptive access policies, automatically adjusting or blocking access based on those attributes rather than relying on static, manually maintained rule sets. This automation reduces administrative overhead and improves consistency, since policies can adapt to changes in user roles or application context without requiring manual reconfiguration each time.
Yes, Seqrite ZTNA integrates with existing identity providers (IdPs) rather than requiring organizations to replace their current identity infrastructure, while also supporting local user management with passwordless OTP-based authentication as an alternative. This flexibility lets organizations layer Zero Trust access controls on top of their existing identity investments rather than undertaking a disruptive, ground-up identity system migration.
ZTNA significantly reduces, though doesn’t entirely eliminate, lateral movement risk by scoping access to specific applications rather than the whole network, meaning a compromised credential grants an attacker access only to what that credential was explicitly authorized for. Combined with continuous verification and device posture checks, this containment effect is one of ZTNA’s core security advantages over VPN’s broader, trust-once network access model.
Yes, ZTNA is suitable for small and mid-size businesses as well as large enterprises, since its cloud-native, SaaS-delivered architecture eliminates the need for the complex on-premise VPN infrastructure that historically made strong access controls harder for smaller organizations to implement. This lower infrastructure burden means smaller organizations can adopt Zero Trust principles without the dedicated IT resources that a traditional VPN and network security stack would typically require.
Migration timelines from VPN to ZTNA vary by organization size and application complexity, but a phased rollout, starting with a pilot group of users or a subset of applications, typically allows organizations to transition over weeks rather than requiring a disruptive all-at-once cutover. Because ZTNA operates alongside existing identity providers and doesn’t require replacing network infrastructure outright, organizations can generally run VPN and ZTNA in parallel during the transition period to minimize business disruption.
