SECURITY ARCHITECTURE & IMPLEMENTATION
SECURITY ARCHITECTURE & IMPLEMENTATION
Avalon turns a growing backlog of security findings into closed, evidence-backed fixes on a predictable schedule, without breaking the systems the mission runs on.
Avalon takes your backlog of open vulnerabilities and audit findings and fixes them in prioritized waves, testing patches first so mission systems don't break, then hands back documented proof that each fix worked, on CISA's new BOD 26-04 clock.
THE PROBLEM & THE APPROACH
The Challenge
Our Approach
CISA's BOD 26-04 (June 2026) gives civilian agencies as little as three calendar days to fix the most dangerous flaws and requires checking whether attackers already got in, a tempo most agency O&M staffing models were never built for.
Avalon triages every finding against BOD 26-04's four-variable model, assigns the correct remediation clock, and coordinates the mandatory forensic-triage step for top-tier findings alongside the fix.
Two decades of federal investment in scanning built world-class visibility into vulnerabilities without funding the labor to close them, most agencies can tell you exactly how many open findings they have, far fewer can staff the closure rate the findings require.
Avalon delivers a closure pipeline, not just deployment labor: findings intake and normalization across every scanner and report, wave-based patch engineering, and rescan validation with before/after evidence for every finding.
Patches deployed without testing break mission applications, which then makes system owners refuse future patching, a self-reinforcing cycle that leaves known flaws open indefinitely.
Every wave runs through a defined test ring before deployment, with a written rollback plan and phased maintenance windows scheduled through the agency's own change advisory board.
A meaningful slice of every federal backlog can't be patched at all, legacy systems, vendor end-of-life products, and frozen mission applications that a patch would break.
Avalon engineers and documents compensating controls, network isolation, virtual patching, privilege reduction, with an explicit residual-risk statement the authorizing official can act on.
CORE CAPABILITIES
Normalizing every scan export and audit finding into a single deduplicated backlog, prioritized against BOD 26-04's four-variable model.
Testing, staging, and deploying fixes through the agency's own tooling and change process, with a rollback plan on every wave.
Rescanning and packaging proof that closes findings the way an assessor and the ISSO's POA&M process actually accept.
OUR PROCESS
Privileged-access mechanics, CAB introduction, data intake of scan exports and inventories, and a baseline snapshot date frozen in writing. (Weeks 1–2)
Dedupe and asset/owner mapping, BOD 26-04 clock assignment, and a remediation plan and wave schedule approved by the agency. (Weeks 2–3)
Waves grouped by platform and fix type; each wave runs test ring, CAB approval, deployment window, and validation rescan, with a defined emergency lane for new top-tier items. (Weeks 3–12)
Closure evidence packages assembled per finding and POA&M input rows delivered on a rolling basis, concentrated in the final weeks.
Metrics report, residual-risk memo, and runbook handoff, with the option to transition into a recurring managed operation. (Final 1–2 weeks)
Sprints frequently convert into a twelve-month recurring patch-and-remediation operation with a defined emergency lane for BOD 26-04 top-tier items.
WHY AVALON

Federal Frameworks Addressed
Mobilization Speed as the Product
Avalon fields a senior team in weeks, not the quarter a large integrator needs to assemble one, no subcontractor stack to mobilize, no bench-clearing exercise, and the people quoted are the people deploying.
Weeks, not a quarter, mobilization speed matters most under a three-day clock, and Avalon will pursue the $60K–$250K sprints that fall below a large integrator's opportunity threshold.
Founder-level technical attention on every wave, versus a large integrator's junior-heavy delivery pyramid.
Many small shops can patch; few package closure evidence an assessor accepts without rework. Avalon's authorization-adjacent services mean the evidence format is native, not an afterthought.
BOD 26-04's mandatory forensic-triage step for top-tier findings plays directly to Avalon's forensic and incident-analysis discipline, checking whether the attacker beat the patch, not just closing the ticket.

Then the question is why the backlog is growing and findings keep reappearing. Avalon complements the incumbent: surge burn-down of the aged backlog, plus validation performed by a party independent of the one being measured. If the incumbent is genuinely keeping pace, your dashboard will show it.
Correct, for all of it at once, today. That's why the engagement is structured as bounded waves against a frozen baseline: one enclave, defined findings, senior engineers only, fixed price. We'd rather deliver one boundary impeccably than staff-augment thinly across ten.
Avalon says so plainly and won't dress it up. What we offer instead: named key personnel with verifiable depth, a fixed-price structure that puts delivery risk on us, and a small first task sized so the downside is bounded.
That history is exactly why the method includes a test ring, CAB integration, phased waves, and a written rollback plan per wave. We treat operational risk as a first-class deliverable, not a disclaimer, ask to walk through the rollback runbook before signing anything.
No, and we won't claim it will. Some findings are always unpatchable, authorization is an official's decision, and inspections grade programs, not sprints. What Avalon sells is measurable backlog reduction, directive-clock compliance for defined tiers, and evidence quality.
They get mitigation engineering, network isolation, virtual patching via IPS/WAF signatures, application allow-listing, or privilege reduction, documented with an explicit residual-risk statement the authorizing official can act on, not just left open.
Not necessarily. If the flaw was exploited before the patch landed, the attacker may still be inside, which is exactly why BOD 26-04 mandates forensic triage for top-tier findings, and why this service includes it rather than stopping at the fix.
