Shield helps teams deploy AI safely, with clear controls, real-time protection, and AI-native discoverability.
Your teachers use AI for feedback. Student data stays in your control.
Purfect Shield sits between your teachers and every LLM they use — tokenizing student PII and education records before they leave your district network, rehydrating responses transparently, and producing a hash-chained audit trail that demonstrates FERPA compliance to your board and parents.
$10K/$25K/$45K, two PO line items, published and flat — no per-seat or per-token meter.
As a design partner, your district shapes the education filter pack while getting production-grade student data protection — deployed in one day on your infrastructure.

The Reality
Your teachers are already using LLMs in the classroom. The question is whether student data is exposed.
FERPA Compliance Gap
Teachers paste student essays, grades, and IEP details into LLMs for feedback and differentiation — and FERPA requires that student education records never reach the model provider in cleartext.
Student PII in Grading LLMs
Student names, IDs, and demographic data appear in AI grading and feedback prompts daily. Most districts have no structural controls preventing this data from reaching model providers.
Budget Constraints
Enterprise AI security tools cost six figures per year — far beyond district budgets. Schools need enterprise-grade protection at a price point their bond measures and grants can actually cover.
EdTech Integration Complexity
Districts already run Google Workspace, Canvas, PowerSchool, and dozens of edtech tools. Adding AI security can't mean ripping out the existing stack or hiring a dedicated security engineer.
The Fix
Foundation Tier: enterprise-grade student data protection at $10K, deployed in one day.
Built for K-12 districts and higher ed. No ongoing subscription. No per-seat pricing. You own the source.
Student Data Tokenized Before It Reaches the Model
Student names, IDs, grades, and IEP details are swapped for stable placeholders at the gateway — the LLM provider never sees real student data, satisfying FERPA requirements.
Foundation Tier — $10K, One Day
Purpose-built for K-12 and higher ed budgets. Deployed on your existing infrastructure in a single day with lightweight onboarding. No ongoing subscription, no per-seat pricing.
Design Partner Path
Early education adopters get direct access to our engineering team, co-development of FERPA-specific filter packs, and priority shaping of the education roadmap. Your workflows drive the product.
Works With Your Existing Stack
Google Workspace, Canvas, PowerSchool, Schoology — Shield sits at the LLM gateway layer and doesn't touch your LMS, SIS, or identity provider. Drop it in without changing how teachers work.
See it on your classroom workflows.
We'll deploy Shield in front of your teachers' AI grading and feedback tools, walk your IT and compliance teams through the FERPA audit trail, and show you exactly how student data is tokenized before it ever reaches a model. One day. Your infrastructure. Foundation Tier pricing.

FAQ
Education LLM Security Questions
Is Purfect Shield FERPA compliant?
Yes. Shield tokenizes student education records — names, IDs, grades, IEP details — before they leave your district network. The hash-chained audit trail provides verifiable evidence that student data never reached a model provider in identifiable form. This satisfies FERPA's requirement that education records remain under the educational agency's control.
Can districts afford Purfect Shield?
Foundation Tier is $10K — purpose-built for K-12 and higher ed budgets. Compare to enterprise AI security tools costing six figures per year with recurring subscriptions. Shield is a one-time perpetual license with source code delivery, no per-seat pricing, and no renewal fees. Many districts fund this through bond measures or technology grants.
Does Shield work with Google Workspace for Education?
Yes. Shield sits at the LLM gateway layer and does not touch your LMS, SIS, or identity provider. It works alongside Google Workspace, Canvas, PowerSchool, Schoology, and any other edtech tool. Teachers continue using their existing workflows — Shield operates transparently at the network boundary.
How does Shield handle student IEP and special education data?
IEP details, accommodations, and special education records are detected and tokenized by Shield's education filter pack before reaching any model provider. The data is rehydrated transparently in model responses so teachers see real information while the LLM provider only sees placeholders.
Can teachers still use their preferred AI tools?
Yes. Shield is provider-agnostic — it works with any OpenAI-compatible endpoint including ChatGPT, Claude, Gemini, and local models. Teachers continue using the AI tools they prefer. Shield's protection is transparent: they write the same prompts, paste the same context, and get the same results — just with student data automatically protected.
How long does deployment take in a school district?
Foundation Tier deploys in one day including FERPA-aligned filter pack configuration and gateway deployment on your district infrastructure. No new hardware required. Shield runs as a single Go binary. Your IT team receives full source code at handoff and can self-maintain indefinitely.
