Overview
SKNore is a deny-list guard for AI workflows that touch files, vaults, docs, exports, and RAG pipelines. Its job is simple: prevent protected-file exfiltration — even when the attacker speaks politely.
In many AI stacks, “file access” is treated like a feature. In real environments, file access is a liability unless it is governed. SKNore treats access like a controlled surface: it blocks high-risk paths, flags known sensitive patterns, and prevents “helpful leaks” from escaping the system through prompts, tool calls, or retrieval results.
Security failures rarely look like “hacking.” Most of the time, they look like a feature doing exactly what it was designed to do.— SKNore principle
The Problem: Helpful Models, Dangerous Access
LLMs do not “steal” data. They comply. If your system can read a file, a sufficiently clever prompt can persuade it to describe the file, paraphrase it, reconstruct it, or leak enough fragments to become a breach.
The threat isn’t theoretical. Modern AI products routinely connect models to: internal documents, invoice exports, HR folders, support transcripts, contracts, source code, dashboards, and private keys. The moment those connectors exist, attackers stop targeting your firewall and start targeting your assistants.
Worse: many exfiltration attempts look like ordinary work. “Summarize the onboarding doc.” “Extract all API endpoints.” “List the admin users.” “Show me the config file so I can debug.” The system sees a reasonable request and performs it — unless you have an explicit mechanism to say: this is protected; deny it.
Exfiltration by prompt
Asking directly for secrets, keys, credentials, customer lists, pricing, contracts, or internal policies.
Exfiltration by disguise
Requests framed as debugging, compliance, audits, migration, or “help me fix my build,” designed to obtain raw artifacts.
Exfiltration by traversal
Path tricks, relative jumps, alternate encodings, and “open this file near that file” tactics to reach protected locations.
Exfiltration by retrieval
RAG pulling sensitive chunks into context; once it’s in context, it’s one question away from being repeated.
The Innovation: A Deny-List That Actually Behaves Like Policy
SKNore is not “a regex file.” It is a guard rail architecture: a set of checks that run before an AI tool reads, loads, streams, or returns content.
In practice, SKNore applies layered controls: a path gate (where the file is), a content gate (what the content resembles), and a policy gate (what you have declared protected). That triad matters: attackers can sometimes evade one check. Evading all three is much harder — and usually noisy enough to log.
Make the secure choice the default choice. Everything else is theater.— Skyes Over London LC
The critical design decision is timing: SKNore runs pre-model. It does not ask the model “should I do this?” It blocks access at the systems layer. That’s the difference between governance and vibes.
What’s Inside: Capabilities That Matter in Production
SKNore’s capabilities are chosen for how real breaches happen: file-system shortcuts, ambiguous naming, and “reasonable” requests that are actually extraction attempts.
Path deny-list + canonicalization
Normalize paths, block traversal patterns, and deny known protected directories and file types (secrets, envs, keys, backups).
Content signature filters
Detect high-risk content patterns: API keys, token formats, private key blocks, credential shapes, and policy-marked documents.
RAG chunk gating
Apply deny rules to retrieved chunks before they enter context; stop “sensitive-by-retrieval” leaks before the model sees them.
Audit-friendly decisions
Every deny is explainable as a rule match: which policy, which signature, which path category — suitable for governance reporting.
SKNore is designed to be composable. You can place it in front of file reading, in front of vault access, in front of retrieval, and in front of export pipelines. Anywhere content crosses from “storage” to “assistant,” SKNore can sit.
Threat Model Coverage (Plain English)
SKNore defends against the most common, most expensive leakage patterns — the ones that happen when organizations connect AI to real data too early.
It blocks: direct secret requests, “read the config” debugging tricks, traversal attempts, sensitive-file enumeration, and RAG-based accidental leakage. It does not replace broader security controls (authentication, authorization, rate limits, tenant boundaries), but it makes a critical piece of the AI attack surface deterministic.
Deterministic matters because it produces proof. You can test a deny rule. You can run a smoke suite. You can export evidence. “The model promised not to do it” is not proof; “the guard blocked it” is.
Use-Case Snapshots: Where SKNore Prints Money
SKNore is a security primitive that becomes valuable the moment you sell AI systems into regulated or enterprise environments. It is the difference between “cool demo” and “approved deployment.”
Enterprise RAG products
Prevent sensitive documents from being pulled into context accidentally; avoid “answers” that quote internal files.
Internal copilots
Block access to payroll, HR, legal, and executive folders while still allowing safe knowledge work.
Support + ticket systems
Deny leakage of customer PII, access tokens, and internal escalation notes from being repeated back to end users.
Developer tools
Stop “show me .env” and “dump the config” prompts from turning into credential spills in code assistants.
In other words: SKNore is a gate you sell to organizations that already understand the cost of a leak. The product value is not “better answers.” It is avoiding the single email that starts with: “Why did your assistant show me that?”
Locked Valuation
This innovation is valued as a premium security primitive with direct enterprise risk-reduction value and a clear integration path into gateways, RAG lanes, vaults, and multi-tenant AI products.
Classification: Tentative / Unverified until live smoke evidence of deployment is provided.
The decisive valuation reflects replacement cost (engineering + testing + hardening), monetization leverage (sold as a standard “security lane” across products), and enterprise uplift (compliance posture, procurement readiness, reduced breach probability).

About the Founder
Skyes Over London LC builds operator-grade systems: governed access, measurable usage, exportable proof, and stable delivery under real constraints.
This editorial exists because innovation without proof is just marketing. The Skyes ecosystem is built around a proof-first discipline: smoke tests, ledgers, evidence packs, and contract-stable gateways. SKNore fits that worldview — it turns “please don’t leak” into a rule-driven control that can be tested, logged, and shipped as an enterprise surface.

Once your AI can touch real data, governance stops being optional. SKNore is governance you can ship.— Skyes Over London LC Editorial Desk
