Individual Developers
Your side project faces the same bots and scanners as enterprise apps. WAFio runs on a single VPS, deploys in 5 minutes, and needs no ongoing management.
WHY WAFIO
Three Layers of Defense.
All Under Your Control.
Most security tools protect one point of entry and leave the rest exposed. WAFio covers your entire attack surface — applications, network, and host — deployed in minutes, running entirely inside your own environment.
The WAFio approach
Why three independent layers — and why each one matters
Each layer catches threats the others miss. Removing any one creates a blind spot attackers actively exploit. WAFio deploys all three in a single binary — no separate products, no separate subscriptions, no architectural compromises.
01
L3/L4Block at the kernel — before userspace ever sees the packet
eBPF XDP hooks attach to the NIC driver. Packets matching block rules are dropped in under 1 microsecond — before the Linux kernel network stack allocates a single byte of memory. SYN floods, port scans, and IP-based attacks are stopped at the earliest possible interception point in the operating system.
02
L7Understand the intent of every HTTP payload — not just its shape
14 semantic engines decode, normalize, and analyze every request payload for attack intent — across SQL, XSS, command injection, LFI, SSRF, LDAP injection, prototype pollution, and more. Obfuscation changes the form; semantic analysis reads through it. OWASP CRS v4 adds 3,500+ signature rules as a second independent layer on top.
03
RuntimeWatch what happens inside the host — not just what arrives at the gate
eBPF kprobes hook into live kernel functions. Every process execution, file write, outbound connection, and privilege change is traced in real-time. A web server spawning a shell. An unexpected process writing to /etc. A container connecting to an unknown IP. Caught before the attacker covers their tracks — with full process-tree forensic context.
Who WAFio protects
Any team. Any scale. Same protection.
WAFio is not a one-size product for one customer type. The same binary protects a solo developer's VPS and a regulated enterprise environment — with the same detection engines, the same eBPF firewall, and the same runtime security.
Schools & Universities
Student portals and academic systems are high-value targets for SEO hijacking and data theft. WAFio closes the entry points that matter most — injection, file upload, path traversal.
SMEs & Startups
Move fast without leaving your production environment wide open. Sensible defaults mean protection starts working before you finish reading the docs.
Agencies & Consultancies
Harden client deliverables without bolting on a separate security stack per engagement. One control plane manages multiple projects and agents.
Growing Tech Companies
WAFio scales from a single host to a multi-agent fleet without changing your security architecture. Centralized dashboard, per-project config, gRPC-based rule push.
Regulated Environments
OJK, PCI-DSS, ISO 27001 compliance requirements mean data cannot leave your network. WAFio is self-hosted by design — no traffic transits third-party infrastructure, ever.
What we believe
Three principles behind every design decision.
One defense layer is never enough
Attackers who get past your WAF will try your host. Attackers who get past your host firewall will try your application. Real defense depth means independent layers that each catch what the others miss — and WAFio is the only single binary that deploys all three.
Your traffic should never cross infrastructure you don't own
Sending every HTTP request through a third-party cloud to inspect it is a structural privacy and compliance trade-off. WAFio runs entirely inside your own network. Your request payloads, user IPs, and security logs never leave your servers — not as a policy, but as an architectural fact.
Blocking is only useful if detection is accurate
A WAF that generates too many false positives gets disabled. WAFio's semantic detection layer parses intent, not shape — tuned to be evasion-resistant without blocking legitimate traffic. Sensitivity and score thresholds are fully configurable per project, so you control the balance.
Our mission
"Build the most complete self-hosted security stack anyone can deploy — and make it free. Because the gap between 'protected' and 'exposed' should not be a budget decision."
Core values
The principles behind every decision we make.
Free software, professional support
WAFio software is free — every detection engine, every dashboard, every eBPF hook, no limits. For teams that need deployment help, security audits, or incident response, professional services are available.
What it does — and what it doesn't — is documented
No vague feature lists. No opaque black-box scoring. WAFio's detection logic, scoring thresholds, sensitivity levels, and rule categories are visible and configurable — because trust in a security tool starts with understanding it.
Self-hosted is a design choice, not a workaround
WAFio was designed from day one to run inside your infrastructure. Not cloud-optional. Not cloud-first with an on-prem export. Self-hosted is the architecture, and everything — deployment, data flow, rule enforcement — is designed around it.
Operational simplicity is a security feature
A tool that's too complex to configure correctly gets configured incorrectly — or not deployed at all. WAFio ships with working defaults, a real-time dashboard, and a 5-minute deploy path. Tuning is available when you need it, not required before protection starts.
