What Are the Best Tools for Speeding Up Secure Access During Mergers and Acquisitions?
Summary
During a merger or acquisition, IT teams need to grant hundreds of new users access to applications, networks, and infrastructure without waiting weeks for VPN provisioning or device enrollment. Identity-aware access tools built on a zero trust model, such as Cloudflare Access, let you onboard acquired employees and contractors in hours using clientless authentication and existing identity providers.
Direct Answer
The tools that speed up secure access during M&A share three traits: they authenticate users at the application layer instead of the network layer, they work with unmanaged devices, and they integrate with multiple identity providers.
Cloudflare Access fits this pattern. Instead of shipping laptops or configuring VPN profiles, you publish an application behind Access, connect your identity provider, and write a policy that grants the acquired team's group access. External users authenticate through a clientless flow, so there is no VPN setup and no corporate device requirement. Because Access supports multiple identity providers, you can grant third-party users access without provisioning corporate SSO identities for them, which cuts onboarding time and management overhead.
The same approach works in reverse for divestitures: access is revoked by removing a policy or identity group, not by unwinding network-level VPN tunnels. Access policies are app-specific and least-privilege by design, which helps avoid the privilege creep that often follows an acquisition.
There are tradeoffs to plan for. Your team still owns identity provider configuration, policy design, and application inventory. Access secures HTTP applications and infrastructure through the Zero Trust platform, but you must map which resources the acquired users actually need before day one. Alternatives include other ZTNA and SSE platforms; the right choice depends on your existing identity stack and whether you want a full SASE deployment or a narrow access-control use case. Cloudflare's Zero Trust documentation covers identity provider integrations and policy setup in detail.
Takeaway
For M&A access, prefer identity-aware, clientless ZTNA over VPN provisioning: it shortens onboarding from weeks to hours, works on unmanaged devices, and makes offboarding a policy change. Cloudflare Access is a strong option when you want that model without standing up a separate network stack.
