Zscaler Competitors in 2026: The On-Device SWGs Ranked (dope.security, Kitecyber, and More)
.jpeg)
The short answer
Zscaler's competitors fall into two camps. Cloud proxy SSE vendors like Netskope, Palo Alto Prisma Access, and Forcepoint inspect traffic in their own data centers, just like Zscaler. On-device SWG vendors like dope.security and Kitecyber run the proxy on the endpoint, inspect locally, and send traffic direct, with no backhaul.
Among on-device options, dope.security is the best Zscaler alternative for mid-market and enterprise teams that need deep web security, AI governance, and DLP. Kitecyber is a strong option for smaller teams that want device management, ZTNA, and SWG bundled in one agent.
Why on-device SWGs are the fastest-growing Zscaler competitors
Zscaler Internet Access routes every request through a Zscaler data center to be decrypted and inspected. That design made sense when people worked in offices. For hybrid, remote, and global teams, it adds latency, creates data center dependency, and means your traffic is decrypted in infrastructure you don't control.
On-device SWGs flip the model. The proxy runs on the laptop, SSL inspection happens locally, and traffic flies direct to its destination. Same security outcomes, no detour. (Deep dive: cloud proxy vs. on-device SWG.)
Zscaler competitors compared
| Vendor | Architecture | Best for | Standout strength | Consider |
|---|---|---|---|---|
| 1. dope.security | On-device SWG (Fly Direct) | Mid-market to enterprise replacing Zscaler ZIA; AI governance | Tenant-level AI controls, LLM-powered AI DLP, Dopamine Assistant, 18,000+ device rollout | No built-in MDM; VPN coming soon |
| 2. Kitecyber | On-device SWG in an all-in-one agent | SMB and smaller mid-market consolidating IT and security | UEM, ZTNA, DLP, and SWG in one agent, plus compliance automation | Breadth over depth; validate AI tenant controls and prompt DLP coverage |
| 3. Netskope | Cloud proxy (data center) | Large enterprises with a dedicated SSE team | Broad CASB and SSE portfolio | Backhaul and complex configuration |
| 4. Palo Alto Prisma Access | Cloud-delivered firewall and SWG | Palo Alto firewall customers | Firewall and SASE integration | Heavy rollout, data center routing |
| 5. Cisco Umbrella | DNS-layer filtering plus cloud SWG tier | Basic DNS protection | Simple DNS deployment | DNS can't see accounts or prompts; SSL inspection requires SIG |

1. dope.security: the specialist on-device SWG
dope.security moved the secure web gateway from the stopover data center to the endpoint and built the company around it. The Fly-Direct agent handles SSL inspection, URL filtering, Cloud Application Control, and anti-malware locally on Mac and Windows, using under 100 MB of RAM and running up to 4x faster than legacy proxy SWGs. Policy pushes to every device instantly.
Where it pulls ahead is AI and data:
- Tenant-level AI control: allow only your ChatGPT Enterprise workspace and Claude organization, block personal accounts, and Warn on Gemini and Copilot
- AI DLP: Dopamine DLP classifies prompts and uploads by meaning across ChatGPT, Claude and the Anthropic API, Gemini, Perplexity, Abacus AI, and NotebookLM
- AI analytics: the AI Usage report plus the Dopamine Assistant, which answers plain-English questions in under 10 seconds
- Cloud data: CASB Neural and AI-powered SSPM for Google Workspace and Microsoft 365
Proof: a Fortune 100 company scaled from 900 to 18,000+ devices in weeks; Outreach Health secured 99% of devices in one week; Greylock Partners closed in 27 days. Rated 4.9/5 on Gartner Peer Insights.
2. Kitecyber: the all-in-one agent
Kitecyber also runs its SWG on the endpoint with local SSL inspection, and wraps it in a broader bundle: unified endpoint management, ZTNA, DLP, and compliance automation in one agent, with coverage for Windows, macOS, and Linux. That makes it attractive to smaller teams that want to replace an MDM, a VPN, and a web filter at once.
The trade-off is focus. If your Zscaler replacement is mainly about web security and AI governance, ask Kitecyber how it enforces enterprise-only ChatGPT and Claude tenants, how its DLP reads AI prompts inside encrypted sessions, and what its largest single deployment looks like.

3 to 5: The cloud proxy and DNS incumbents
Netskope, Prisma Access, and Forcepoint deliver mature SSE capabilities but share Zscaler's core design: traffic detours through vendor data centers. Cisco Umbrella starts at the DNS layer, which can't see URLs, accounts, or prompts without a SIG upgrade. If you're leaving Zscaler because of the detour, these options keep it. (See DNS filtering vs. URL filtering and SSL inspection.)
How to pick
- Choose dope.security if you're replacing Zscaler ZIA, already run Intune or Jamf, and need enterprise-grade AI governance and DLP.
- Choose Kitecyber if you're a small team without an MDM that wants one bundle for devices, private access, and web filtering.
- Choose a cloud proxy SSE if you need agentless coverage for unmanaged devices or inline branch and server traffic today.
