SECURITY OPERATIONS & INCIDENT MANAGEMENT
SECURITY OPERATIONS & INCIDENT MANAGEMENT
Avalon turns the EDR your agency already pays for into full-coverage, low-noise, audit-ready detection and response, measured in coverage percentage and time-to-detect, not licenses purchased.
Avalon deploys, configures, tunes, integrates, and validates your endpoint detection and response platform, then proves the result with controlled attack-simulation testing, so the EDR you already own delivers real protection, not just a compliance checkbox.
THE PROBLEM & THE APPROACH
The Challenge
Our Approach
Endpoints remain the most common initial access point into federal networks, and an untuned or partially deployed EDR platform means the agency finds out about an intrusion from CISA, an IG, or the adversary's effects, not from its own console.
Avalon reconciles the agency's authoritative inventory against what the EDR console actually reports, audits agent health, and runs controlled ATT&CK-mapped emulation to prove, with evidence, what the platform would actually catch.
OMB M-22-01 requires FCEB agencies to operate EDR and give CISA telemetry access, the zero trust device pillar requires the same visibility and response capability, and RMF authorization packages need implemented, evidenced SI-4 and IR-4 controls.
Avalon delivers deployment, tuning, and validation aligned to NIST SP 800-61r3, OMB M-21-31, and CIS Benchmarks, and hands over an SSP-ready Control Evidence Package mapped directly to the SI/IR/AU/CM control families.
Default vendor policies in a federal environment generate alert volumes that overwhelm understaffed SOCs, alert fatigue is how real detections get missed inside tools that technically "saw" the attack.
Avalon runs a staged audit-to-blocking progression with measured soak periods, builds custom detections for agency-specific concerns, and reports false-positive rate and alert volume per analyst before and after tuning, a number, not an adjective.
Agencies pay for enterprise EDR licensing while a meaningful fraction of the fleet has no agent, a broken agent, or an agent stuck in audit-only mode, shelfware with a compliance narrative attached.
The EDR Coverage & Efficacy Assessment is a standalone, fast entry engagement that turns that unknown into a defensible coverage number and a costed, prioritized roadmap the agency can act on immediately.
CORE CAPABILITIES
Avalon's strongest entry offer: a defensible coverage number and a controlled, ATT&CK-mapped efficacy test against your platform as deployed today.
Getting the platform onto every device it belongs on, migrated without regression, and moved safely from audit mode to blocking mode.
Connecting the platform to your monitoring stack and handing your analysts the runbooks and validated evidence they need to operate it themselves.
OUR PROCESS
Provision accounts and console access, confirm points of contact, map the change-board calendar, and agree success metrics. (1–2 weeks)
Reconcile inventory, audit policy configuration, and run the controlled efficacy baseline test. (2–4 weeks)
Design the remediation and wave plan, then deploy and performance-validate a pilot ring across every hardware and OS class. (2–4 weeks)
Roll out in waves aligned to your change-board calendar, with exclusions engineering and, for migrations, staged dual-agent coexistence. (4–10 weeks)
Progress from audit to blocking mode, build detection content, integrate with your SIEM and reporting stack, and run the closing ATT&CK retest. (3–5 weeks, overlaps deployment)
Hand off runbooks, run a tabletop exercise, deliver knowledge-transfer sessions, and brief the executive closeout. (1–2 weeks)

Proof-Based Delivery
Most vendors stop at "deployed." Avalon's closing deliverable is an ATT&CK-mapped validation retest reporting coverage percentage, agent-health percentage, median time-to-detect, and false-positive rate, before and after, in writing.
A named senior team is available at award, the assessment starts inside two weeks, not the weeks-to-months a large integrator needs to staff a task order.
No delivery pyramid handing the console to junior staff, the person who scopes the engagement is the person tuning the platform.
Lower overhead means materially lower price for senior-only delivery, and every dollar scores toward the agency's small-business and HUBZone goals.
Runbooks and containment procedures are written by the same people who deliver Avalon's incident response and forensic analysis service, so they hold up if a real incident follows.

Federal Frameworks Addressed
Owning is not operating. Three questions tell you what you actually have: what's your coverage percentage against your authoritative inventory, when did you last test detection and what happened, and what's your false-positive rate? If any answer is "not sure," that's exactly what the assessment exists to answer with evidence.
CDM provided the tooling and dashboards, and CISA's telemetry access under M-22-01 is a real federal backstop, but it isn't your SOC, and CISA's proactive support capacity has contracted materially. Detection and response inside your agency remain your responsibility, and tuned, operated local response is not the same thing as an access arrangement.
An independent validation is something the incumbent should welcome. Avalon's scope is surgical, fixed-price, and doesn't touch the incumbent's contract, the retest either confirms their work, worth having in writing, or surfaces gaps the agency needs to know about either way.
No, and we won't blur that line in a proposal. This service implements and validates the detection capability and delivers SSP-ready implementation evidence for controls like SI-4 and IR-4. It doesn't complete the CISA telemetry-access relationship, grant an ATO, or certify CMMC, those rest with the agency, the Authorizing Official, and a C3PAO respectively.
That risk is exactly why the methodology exists: a pilot ring across every hardware and OS class, performance baselining before and after install, an audit-mode soak before any blocking, and engineered exclusions built with system owners at the table, with documented rollback for every wave.
The honest answer: fixed scope, named key personnel with verifiable platform certifications, a stated concurrency limit, and no dependency on hiring to deliver. Small firm, small blast radius, senior hands on the console.
A mid-size environment (2,500–15,000 endpoints) typically runs 12–20 weeks end to end. Small, single-enclave environments compress to 8–12 weeks; large, multi-enclave environments run 6–9 months, driven more by enclave count and change-board cadence than raw endpoint count.
