Zero Trust SWG · Made in India · 20+ Years
Your perimeter is the last line of defence. Still holding?
SafeSquid SWG enforces Zero Trust web access at the network perimeter — stopping threats before they reach your users, not after.
Trusted by enterprise security teams
The problem
The web is your largest attack surface.
Hidden inside what your gateway already trusts.
Four critical attack surfaces
Where your gateway leaves the door open.
Adversaries hide behind what you trust — your enterprise zone, your perimeter, and the approved-looking destinations in between.
Modern attacks hide inside trusted web sessions — tap to explore in detail.
Perimeter
Sanctioned Web Traffic
Attackers embed payloads inside cloud services your SWG explicitly trusts — Google Drive, Dropbox, OneDrive. The policy says allow. The malware walks in.

Destinations
Trusted Destinations
Compromised CDNs, typosquatted domains, and legitimate sites injected with malicious scripts bypass URL blocklists entirely. Allowed by design. Dangerous by reality.
Learn More
Enterprise zone
The Browser
Zero-day browser exploits, drive-by downloads, and malicious extensions execute entirely inside the browser — before endpoint protection even activates.
Learn More
Enterprise zone
Insider / Compromised User
A privileged user uploading sensitive files to personal cloud. A compromised account exfiltrating data over encrypted channels. Your perimeter lets it through.

Added risks because of AI
Generative AI expanded the web attack surface.
AI tools, SaaS platforms, and shadow apps create new pathways for data exposure — through the same trusted browser sessions your perimeter already approves. Same sessions. New exposure.
- Public LLMs
- Custom agents
- AI SaaS tools
- Shadow SaaS
- Code generators
- File sharing

AI accelerates productivity. It also accelerates risk.
Zero Trust starts with understanding every web session →
Shadow IT
Shadow AI & SaaS sprawl
ChatGPT, Copilot, and unsanctioned AI tools spread across teams faster than security can inventory them — outside IT control and outside your SWG policy.

Data egress
Sensitive data movement
Proprietary code, customer records, and confidential prompts flow into public LLMs and paste sites over the same HTTPS sessions your gateway already allows.

Policy gap
Policy overload & blind spots
URL lists and category blocks can't see session context. Security teams lack real-time visibility into what users paste, upload, or generate inside AI workflows.

Gaps in existing SWGs
Legacy web security was not built for Zero Trust.
Legacy proxies and static controls create blind spots that attackers exploit to hide and move freely — while your policy still reads “allow.”
Four failure modes in legacy SWGs — tap to explore in detail.
Result: false trust decisions. Attackers move through blind spots. Data leaks. Legacy security allows risk to pass as normal.
Part A
What Zero Trust means
Never trust. Always verify. Continuously.
Zero Trust is not a product — it's a posture. It requires verifying every request, every user, every payload, every time — regardless of where the request originates. Perimeter alone is not enough. “Inside the network” is not a trust signal.
Part B
Performance vs security trade-off
Admins disable inspection to preserve speed.
Legacy multi-process SWGs degrade severely under deep inspection load. The real-world result: security teams disable HTTPS inspection to stop complaints about slow browsing. A security tool that runs without its most critical feature is not a security tool.
Part C — Four unmet pillars
Where traditional SWGs fail.
Four layers a legacy gateway can't hold — without crippling performance.
Destinations
Destination reputation ≠ payload safety.
URL allowlists pass traffic through. Malware rides inside Google Drive, SaaS APIs, and approved cloud apps your policy explicitly trusts.
Gap: Unchecked payload
The Browser
Inspection ends at the gateway.
JavaScript, WebAssembly, and DOM execution happen on the endpoint — after your SWG has already cleared the session.
Gap: Post-gateway execution
Insiders
Trust doesn't expire with the login.
Compromised credentials and privileged users exfiltrate over channels the perimeter explicitly allows — with no continuous re-verification.
Gap: Session not re-verified
Data Egress
Encrypted traffic is a blind spot.
Sensitive data exits via HTTPS and WebSockets — invisible to gateways that inspect headers and URL lists, not content.
Gap: Encrypted blind spot

The solution
Introducing SafeSquid SWG
Zero Trust web security. No trade-offs.
Designed from first principles as an HTTP(S) proxy for Zero Trust — not retro-fitted from a web cache. Every inspection engine shares full session context inside one tightly coupled architecture, in real time.

Innovation 01
The paradigm shift: multi-threaded, not multi-process.
Eliminating the processing bottleneck through shared memory architecture — so deep inspection never trades off against speed.
Legacy · Multi-process
External IPC. No shared context.
- Structured data locked inside isolated processes
- External IPC chains to share context
- Payload copied for every parallel scan
SafeSquid · Multi-threaded
Shared memory. Parallel by design.
- Compact multi-threaded network application
- Security engines in shared memory — zero-copy
- Parallel threads, one live session context
Benefit
Zero-copy handoff between engines · Efficient parallel processing · No latency penalty for deep inspection
Multi-threaded vs multi-process — tap to explore in detail.
Innovation 02
Contextual intelligence: a neural network for traffic.
Every processor runs in parallel on the same data — no copies, no serial bottleneck. Results fuse into one contextually-aware decision per transaction.

Neuron collaboration
Profiling neurons classify protocol and payload structure together — not in isolation.
Real-time intelligence
Structured data pools share context across every active connection instantly.
Correlation
Unravels protocol and payload, validates against policy before re-transmission.
