# FEDLIN LLC > FEDLIN is a boutique infrastructure security practice for mission-critical, regulated environments. It secures a client's internal estate (identity, endpoints, network, workloads, DNS, and the cryptographic layer) across cloud, on-premises, and hybrid, through architecture, engineering, assurance (QA and penetration testing), cryptography and post-quantum migration, and GRC. Every engagement separates the architecture decision (what the controls should be, and why) from the engineering (built and running in the client's own environment), delivered together or as standalone deliverables. > > The work is hands-on engineering, delivered inside the client's environment, with evidence produced by systems that are actually running. It is distinct from advisory, audit, certification, and attestation services; no FedRAMP authorization is claimed, and nothing FEDLIN runs becomes a client system of record. > > The current lead offer is a mandate-triggered cryptographic readiness ladder. It opens with a free first-pass scan of one system, run inside the client's boundary, that returns a vulnerable-asset list. From there: a paid cryptographic inventory that produces a CycloneDX CBOM and a prioritized migration roadmap mapped to the applicable control regime (Phase 1 evidence for teams under OMB M-26-15); deeper multi-system capture where clusters or source exist; and an annual re-inventory that keeps the evidence current. It is relevant to federal PQC mandates (OMB M-26-15, CNSA 2.0) and to defense and critical-infrastructure flow-down reached through teaming. > > The market qualifier is mission-critical and regulated; the unifier is a mandate. The credential base spans NERC/FERC, PCI, HIPAA, and SOC 2. Securing self-hosted, in-boundary AI (agent and MCP boundaries, access scoping, agentic audit logging, mapped to NIST AI RMF and NIST 800-53) is an adjacent capability delivered on the same crypto-agile foundation. Website: https://fedlin.com ## The cryptographic readiness ladder (current front door) The lead offer. A mandate-triggered ladder, entered at the free scan, that walks a buyer from exposure to a defensible roadmap and the engineering to execute it. - [Post-Quantum Readiness](https://fedlin.com/services/post-quantum-readiness/): The front door. It opens with a free scan of one system (run in the client's boundary, returning a vulnerable-asset list from public TLS metadata), then a paid cryptographic inventory that captures live cryptography as a CycloneDX CBOM, scores each asset against the PKI Consortium's PQC Maturity Model (PQCMM, six levels), maps it to its CNSA 2.0 target, and returns a sequenced migration roadmap, all produced inside the client's boundary. Deeper multi-system capture (runtime, FIPS, HSM) and an annual re-inventory follow. Phase 1 evidence for OMB M-26-15; supply-chain buyers increasingly require a PQCMM score alongside a roadmap. - [Crypto-Agility Engineering](https://fedlin.com/services/crypto-agility/): The follow-on that executes the migration the roadmap defines: email authentication (DKIM), edge TLS and cipher suites, workload identity (SPIFFE/SPIRE), long-lived record signing (SLH-DSA / FIPS 205), and post-quantum key establishment (ML-KEM). The cryptographic engineering that runs across every FEDLIN service. ## Security engineering services - [Services overview](https://fedlin.com/services/): The full FEDLIN catalog, a mission-critical cryptographic and security assurance practice. Every engagement is a fixed-fee build entered where the risk is, scaling from a single requirement to a full embedded security program. - [Vulnerability Remediation](https://fedlin.com/services/vulnerability-remediation/): Close a queue of findings (post-pentest, post-incident, pre-M&A, or audit backlog) with engineering and auditor-ready evidence. A follow-on that remediates the exposures an inventory or a test surfaces. - [GRC Engineering](https://fedlin.com/services/grc-engineering/): NIST AI RMF controls and SOC 2 evidence deployed at the infrastructure layer, mapped to ISO 42001, with GRC platform integration (Vanta, Drata) wired to controls that are actually running, so evidence is a byproduct of the build. Proof of tier: the crosswalk and evidence beneath the engineering. - [Penetration Testing](https://fedlin.com/services/penetration-testing/): Manual exploitation of web apps, APIs, networks, cloud, and AI surfaces, with CVSS-scored findings, reproduction steps, and a retest. - [Edge Security](https://fedlin.com/services/web-api-security/): The ongoing security layer for the edge: WAF, security headers, TLS hardening, and DMARC/DKIM/SPF, available as a managed tier (Foundation, Protection, or Assurance) or as scoped one-time engagements. Also the required stewardship tier for a Secure Private AI Node. ## AI security (adjacency) - [Self-Hosted AI Security](https://fedlin.com/services/agentic-mcp-security/): For teams running AI on infrastructure they own. An MCP security audit maps the access surface of every MCP server, finds excessive agency, over-scoped tools, and prompt-injection paths, then locks it down with access scoping, context boundaries, and agentic audit logging (NIST AI RMF and the OWASP LLM and Agentic Top 10 mapped). It also configures a Secure Private AI Node (BYOD, We-Provision, or Cloud-hosted) with an Edge Security retainer for ongoing hardening. Delivered on the same crypto-agile foundation as the cryptographic work, positioned as an AI-BOM and AI-governance adjacency beneath the cryptographic front door. ## About FEDLIN - [About](https://fedlin.com/about/): FEDLIN LLC is a security engineering firm, a New Mexico limited liability company operating from Middle Tennessee and serving clients nationwide, led by Jeremiah Coakley, Principal Security Architect.

Transport is Streamable HTTP at `https://mcp.fedlin.com/mcp`. Tools: `scan_post_quantum` (post-quantum / hybrid ML-KEM TLS key exchange), `scan_domain_trust` (DNS, TLS, certificates, and email authentication: SPF, DKIM, DMARC, DNSSEC), and `scan_security_headers` (HTTP security headers). Each takes a public hostname, is rate-limited, and is passive and public-surface only. ## Optional - [Managed Web Services](https://fedlin.com/services/managed-web-services/): A natural extension of the FEDLIN security program into a managed web presence, delivered as Continuit Web (a partnership with Canvex Studio for web and SEO, and AutomateShift for automation).
