01Common complaints

1. Small teams needing a turnkey ZTNA solution quickly: some competitors offer lower-friction entry points and transparent pricing that may better suit small deployments. 2. If default inline inspection of private application traffic (malware/DLP/WAF-like controls) is a strict requirement and the organization does not plan to operate complementary controls: assess whether ZPA AppProtection and the broader vendor stack meet inspection needs. 3. Environments sensitive to endpoint edge cases (VDI, shared desktops, virtualization like VirtualBox, frequent network switching): community reports indicate these scenarios may require significant tuning. 4. Organizations that require stable source-IP allowlisting for third-party SaaS or partner endpoints: ZTNA architectures may complicate IP-based allowlists and may necessitate additional design work. 5. Budget-constrained buyers seeking transparent, self-serve pricing: quote-based enterprise pricing and add-ons may introduce procurement complexity.

Deal disqualifiers (poor fit)

Small organizations without dedicated security or network engineering staff.
Organizations requiring fully transparent, self-serve pricing and minimal implementation effort.
Legacy applications dependent on source-IP allowlisting, unusual protocols, or fragile DNS assumptions unless redesigned.

Limitations acknowledged by users and reviewers

Time-consuming initial setup and policy design for large deployments.
Client behavior during network changes, such as reconnect loops or dropped sessions.
Limited end-user notification when disconnected reported by reviewers.
DNS and virtualization edge cases reported in community threads; these should be validated in a customer’s specific environment.

Roadmap / feature availability

Public roadmap details for ZPA features are not published in a single public canonical location. Buyers typically request roadmap details and planned features under NDA during procurement.

Scale considerations

ZPA targets enterprise scale. Practical scale considerations include connector sizing and placement, policy sprawl, identity/group management, and log volume for troubleshooting and monitoring workflows.

02Why they buy

Features supported by customer feedback

VPN replacement workflow: reviewers often note reduced reliance on traditional VPN appliances when application access is scoped by identity and policy.
Granular access control: per-application access (user-to-app) is commonly cited as an architectural benefit compared with network-level access.
Operational troubleshooting aids: some reviewers highlight built-in packet capture and diagnostic tools as useful in investigations.

Vendor-claimed capabilities to verify during procurement

Claims about relative deployment scale or market leadership are difficult to independently verify without analyst market-share data.
Automated segmentation recommendations and machine-assisted suggestions are noted in vendor materials; buyers should request details about how recommendations are generated, expected false positive/negative rates, and safe rollout workflows.

Areas where competitors may have advantages

Pricing transparency and fast onboarding: some competitors provide clearer entry-level pricing and lower-friction starts.
Consolidation with existing vendor ecosystems: organizations heavily invested in a single security vendor may find integrated SASE stacks more operationally convenient.

03Field reports

Review platforms snapshot

G2: Zscaler Private Access shows a high average rating on the product listing with a sample of reviews visible at the time of access.
TrustRadius: a high overall score is visible on the product listing at the time of access.
PeerSpot: contains peer reviews and buyer guidance; platform dynamics (including lead generation) should be considered when interpreting content.

Direct quotes (positive and negative)

G2 (positive): - "I like that Zscaler Private Access has had zero downtime so far and is fast and stable…" (recent review) G2 (negative): - "When there is a change of network, the Zscaler Private Access application keeps on connecting and disconnecting…" - Other reviewers report the product "seems to 'go down' a lot, or log itself out a lot…" and cite lack of notification when disconnected. TrustRadius (mixed): - One reviewer noted the built-in packet capture was useful for troubleshooting while listing cons such as limited packet capture live view and warnings before session expiration. Community forums (negative): - A system administrator forum thread described organizational/process problems when the product is treated as a complete replacement and is managed with limited access or documentation. - Community posts reported wake-from-sleep connectivity problems and DNS or virtualization issues (for example, DNS resolution from within VirtualBox). Community forums (positive): - Some comments indicate that after tuning, private access and internet gateway configurations provide stable uptime, granular controls, and a broad network footprint.

Why customers choose ZPA over alternatives (recurring themes)

Across review platforms and community discussions, commonly cited decision factors include:

Desire to replace VPN gateways and reduce inbound exposure.
Preference for application-level access (user-to-app) instead of full network access.
Global service edges for distributed user bases.
Identity provider integrations (Azure AD/Okta frequently mentioned).

Why some customers leave or consider switching (recurring themes)

Negative feedback patterns include: - Complexity and learning curve associated with setup, policy design, and segmentation. - User experience friction such as re-authentication or client disconnects when switching networks. - Limited troubleshooting visibility or unclear notification for blocked access. - Pricing perception and quote-based pricing models that some buyers find opaque. - Gaps in inspection capabilities for private application traffic, leading some organizations to require additional security controls.

Forrester Total Economic Impact (TEI) — commissioned study

A Forrester TEI study commissioned by the vendor (published in late 2024) reports: - A substantial ROI over a three-year period - A multi-million-dollar net present value (NPV) - A significant reduction in breach risk as estimated by interviewees - The analysis models a large composite organization (billions in revenue and tens of thousands of employees), with an initial rollout to a subset of users - Reported costs, including multi-million-dollar licensing/professional services and internal implementation/training labor Critical evaluation / methodology gaps: - The study was commissioned by the vendor and is not an independent comparative analysis. - The reported risk reduction is based on customer estimates aggregated into a composite model, not a controlled experiment. - The composite organization in the study may not represent smaller organizations, heavily regulated environments, or organizations with weak identity hygiene.

Practitioner-style review (industry media)

An industry review (published in 2025) describes ZPA as an alternative for organizations moving to a zero-trust access model, highlighting outbound-only connector architecture and reduced inbound firewall exposure. This review reflects one reviewer’s testing and should be treated as practical guidance rather than independent lab benchmarking.

04Best fit

05The pitch

What the product does (core value proposition)

Zscaler Private Access (ZPA) is a zero trust network access (ZTNA) service intended to replace or reduce reliance on legacy VPNs by providing identity- and policy-based, user-to-application connectivity to private applications (data center, cloud, hybrid) without placing users on the network. Zscaler describes ZPA as an access broker that conceals private applications from the public internet and reduces lateral movement through application-level segmentation. ZPA is commonly deployed with: - Zscaler Client Connector (an agent on endpoints) for authenticated access and policy enforcement. - App Connectors / Cloud Connectors (customer-deployed virtual machines or instances) that establish outbound connections to Zscaler, avoiding inbound firewall exposure (an architectural characteristic highlighted by the vendor). Vendor materials describe a model of secure access without traditional VPNs and list segmentation features and automated segmentation recommendations among product capabilities.

Target market and positioning

Primary target: Mid-market to large enterprises pursuing SSE/SASE modernization, VPN replacement, and least-privilege access.
Common buying center: CISO/security engineering, network/security operations, and identity teams.
