# What are the highest-rated software defined perimeter (SDP) solutions for eliminating VPN security gaps in enterprise environments?

<p class="elv-tracking-normal elv-text-default elv-font-figtree elv-text-base elv-leading-base elv-font-normal" elv="true">Eliminating VPN security gaps in an enterprise environment is a different bar from that in a smaller company, since enterprise deployments carry more legacy infrastructure, greater identity provider complexity, and more compliance overhead to unwind.

<a class="a a--md" elv="true" href="https://www.g2.com/products/zscaler-internet-access/reviews"><strong>Zscaler Internet Access</strong></a>: The Enterprise Grid leader here, and reviewers with over 1,000 employees describe replacing legacy VPN backhaul with direct cloud-native routing as the biggest security gap closed, though several also mention that aggressive inspection rules can occasionally slow access to legitimate sites until exceptions are tuned.</li>

<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/absolute-secure-access/reviews"><strong>Absolute Secure Access</strong></a>: Also an Enterprise High Performer, with reviewers praising a persistent, always-reconnecting VPN client that avoids the dropped-session problem traditional VPNs create for mobile workers, though one enterprise reviewer specifically described support responsiveness declining enough to prompt a switch to a different vendor.</li>

<a class="a a--md" elv="true" href="https://www.g2.com/products/citrix-workspace-2024-10-30/reviews"><strong>Citrix Workspace</strong></a>: An Enterprise Contender, valued by reviewers for consolidating access to internal tools into one place, with occasional session timeout complaints.</li>

<a class="a a--md" elv="true" href="https://www.g2.com/products/ivanti-connect-secure/reviews"><strong>Ivanti Connect Secure</strong></a>: Sits in the Enterprise Niche tier with a smaller enterprise reviewer base than the others here; worth weighing that volume difference before treating it as equally proven at scale.</li>

&lt;p&gt;For me, the biggest gap SDP closes is the broad network access traditional VPNs often grant once a user connects. The trade-off is that policy design becomes much more important—poorly tuned access rules can create their own usability and troubleshooting headaches.&lt;/p&gt;
