THE REMEDIATION GAP

Discovery has been outrunning remediation for a decade. Mythos just collapsed the runway.

This was a problem before Anthropic's announcement. Mythos made it impossible to defer.

Found faster than fixed.

A decade of scanner investment produced more findings, not more fixes. The remediation backlog compounded across thousands of codebases.

The constraint moved.

Manual triage and probabilistic agent fixes do not close findings at AI scale. The bottleneck is no longer discovery. It is deterministic, auditable remediation across thousands of repositories.

The gap is the story. Mythos didn't create the remediation problem. It made it unavoidable.

The gap, quantified

Scanning is solved. Remediation is not.

A decade of scanner investment has not produced fix capacity. Mythos collapses the runway. The board now expects an answer for findings the team cannot fix at current pace, and the economics of token-priced agentic remediation do not scale.

Why Doing Nothing Fails

Six pressures every CISO is facing now

Mythos didn't change any of these in isolation. It compressed the timeline on all of them at once.

The downstream CVE flood

Every Mythos-discovered flaw in a kernel, browser engine, or shared OSS library becomes a published CVE in your scanner queue. The backlog multiplies by orders of magnitude before you act on any of it.

Probabilistic fixes don't close findings

LLM-based remediation produces partial fixes. The agent declares victory while you re-prompt it all evening trying to confirm coverage you can never quite pin down. Vulnerability fixes have to be complete to count.

Agents need a deterministic blueprint

An attacker only needs to find one instance of a vulnerability. A defender has to close every instance, or the business stays exposed. Coding agents alone are built for the attacker’s job. Without a recipe, there’s no way to confirm every occurrence has been closed.

Token economics break at scale

Fixing one CVE across two thousand repositories with raw inference pays for the same reasoning two thousand times over, which doesn't scale. A recipe is written once and runs everywhere, so the work is amortized.

You can't upgrade your way out

For end-of-life frameworks like older Spring, the "just upgrade" path is a multi-quarter migration. Mythos doesn't grant that runway, so backpatching into the version you run may be the only path that fits the window.

Board-ready answers, in hours

CISOs will be asked "what is our exposure to the latest Mythos disclosure?" within hours of each release. Without a deterministic remediation pipeline with an audit trail, the honest answer is "we don't know."

Every red team needs a blue team.

Two halves of the same problem, solved by structure rather than competition. Mythos finds a vulnerability. The coding agent equipped with Moderne writes the recipe to close it. The Moderne Platform defends the perimeter, distributing the fix across every repository in your code estate.

How the agent gets a deterministic blueprint.

The Lossless Semantic Tree is the source of the determinism. It is the foundation that makes every other capability below it reliable enough to put a board behind. Six capabilities then turn one finding into one recipe, and one recipe into a fix across the entire portfolio.

OpenRewrite recipes

In an IDE, you trust rename and extract-method refactorings because they're deterministic. OpenRewrite takes that determinism outside the editor and makes it programmatic. Each recipe is a verifiable program that runs the same way every time, against any repository in your portfolio

The Lossless Semantic Tree

The source of the determinism. A type-attributed, semantically complete representation of your code that supports interprocedural, field-sensitive taint analysis. Without the LST, an agent's fix is a probabilistic guess. With it, the agent has a verifiable blueprint to execute.

Portfolio-scale distribution

One recipe runs across thousands of repositories in parallel. The unit economics of fixing one CVE across 2,000 repos should not be 2,000 times the cost of fixing one. With Moderne, it isn't.

Agent Tools and MCP

Connect any coding agent (Copilot, Cursor, Windsurf, Devin, Claude Code) to Moderne via MCP. With LST-based tools in hand, the agent both authors and executes deterministic recipes. Agent-agnostic by design.

Backpatching

For end-of-life frameworks you can't upgrade fast enough, Moderne backports the security fix to the version you're running and distributes it. No forced migration. No runway loss.

Audit and determinism by default

Every recipe run is deterministic and produces a verifiable record of what changed, where, and why. The board-ready answer to "what is our exposure" is a query against the same pipeline that did the remediation.

What Moderne closes

The vulnerability classes Moderne remediates.

Two buckets, depending on where the vulnerability lives. Third-party code you depend on, and first-party code you write. Different remediation paths, the same deterministic recipe model.

Third-party code

Code you depend on

Dependency vulnerability remediation

Upgrade to a fixed version across every repository that pulls the vulnerable package. The same upgrade applied identically, portfolio-wide.

Backpatches for end-of-life frameworks

When upgrade isn't an option, backport the fix to the version you're running and distribute it. The backpatch approach for the frameworks you can't move off yet.

First-party code

Code you write
