An incident-response agent should treat each new case as a fresh investigation informed by verified organizational experience—not as a reason to repeat whatever worked last time. That means grounding analysis in current evidence, retrieving relevant prior cases with their sources and caveats, controlling any actions the agent can take, and updating reusable knowledge only after people verify what happened. The available description of RECALL-X calls it an AI-powered SOC assistant with persistent organizational memory, but does not establish its implementation, evaluation results, or improvement in production. The architecture below is a practical design pattern, not a claim that RECALL-X has been shown to work this way.
What should “learns from every incident” mean?
For an incident-response agent, learning need not mean retraining a model after every alert. A safer, more auditable interpretation is that the system maintains a reviewed collection of incident records and response knowledge, retrieves relevant parts during later investigations, and updates that collection when outcomes have been verified.

Two inputs must remain distinct. Current evidence—such as alerts, logs, and asset state—describes what may be happening now. Past experience can suggest useful hypotheses, queries, and response options, but cannot establish that an old incident’s cause or remedy applies to the current one. The agent should show which evidence supports a conclusion and which retrieved case, if any, informed it.

How the incident-response loop should work
A design for RECALL-X can be organized as a sequence from incoming evidence to reviewed knowledge. Each stage should preserve enough provenance for an analyst to check what the agent saw and why it acted.
1. Ingest and normalize the current incident
Collect relevant alerts, incident tickets, endpoint, network, and authentication logs, plus asset and vulnerability context. Preserve source identifiers and timestamps; normalize formats without discarding the originals or their time context. A missing log source or stale asset record should be visible as a limitation, not silently treated as evidence that nothing happened.
2. Build a timeline and testable hypotheses
Parse current records into a timeline and candidate indicators, then identify what is known, what is inferred, and what remains uncertain. Cadet and coauthors describe targeted query libraries linked to MITRE ATT&CK techniques to extract indicators from raw logs and reconstruct attack sequences. That is one reported approach, not a requirement for every system.
3. Retrieve relevant prior cases and security knowledge
Search both structured incident records and security references. Exact keyword search can find identifiers such as a hostname, hash, or CVE; semantic search can surface conceptually related cases even when their wording differs. Qiu and coauthors describe using vector and keyword retrieval over incident-relevant knowledge, including CVE details and attack procedures, alongside a graph of assets, vulnerabilities, attack methods and stages, and response actions. These are design choices described in that work, not universal standards.
Rank #2
Retrieval should return evidence and context, not just a model-generated summary. Show the source, date, affected environment, and caveats for each suggested case. A superficially similar incident may involve a different asset role, software version, attacker technique, or business constraint.
4. Compare evidence and plan the response
Use retrieved cases to propose investigation steps and possible explanations, then test them against the current incident. Keep alternatives and uncertainty visible; a prior case should not turn a hypothesis into a finding. Gao, Hammar, and Li describe an agent organized around perception, reasoning, planning, and action, with simulated outcomes compared against observations to refine its hypotheses and responses.
Separate recommendations from actions that change systems. An agent might first suggest a query or ask for an analyst decision; disabling an account, isolating a host, or changing a control can have operational consequences. Define which tools are available, validate their arguments, and set approval requirements according to the potential impact. The cited frameworks do not establish one approval policy that suits every organization.
5. Review the outcome and retain a verified lesson
After resolution, have an analyst validate the root cause, relevant evidence, actions taken, their effects, and any unresolved questions. Keep corrections, rejected hypotheses, and failed actions where they can prevent repetition. Only promote a lesson into the reusable collection after review, and mark the conditions under which it may not transfer to another case.
Rank #3
A useful case record can include:
- Incident type, environment, affected assets, and event dates.
- Links or identifiers for source evidence, with timestamps.
- Root cause, confidence, reviewer, and review date.
- Actions taken and observed effects, including failed or reversed actions.
- Known caveats, rejected explanations, and limits on applying the lesson elsewhere.
At retrieval time, surface those fields alongside the suggested lesson so an operator can judge whether it applies. This record format is a design recommendation; it is not a verified description of RECALL-X.
What published results do—and do not—show
Other projects provide examples of incident-response agents, retrieval systems, and evaluation methods. Their reported metrics belong to their own systems and test settings. They are not RECALL-X results, and results from different tasks and environments should not be treated as directly comparable.
| System or study | Reported result | What the result covers |
|---|---|---|
| AIR, by Zibo Xiao, Jun Sun, and Junjie Chen (PMLR, 2026) | Detection, remediation, and eradication success rates each exceeded 90%. | AIR’s evaluated setting. The framework combines incident detection, containment and recovery actions, and guardrail synthesis in an LLM-agent execution loop. |
| Gao, Hammar, and Li (arXiv, 2026) | Recovery was reported as up to 23% faster than frontier LLMs. | Their evaluation on incident logs; it does not establish a general recovery-time gain for other agents or SOCs. |
| Cadet and coauthors (arXiv, 2026) | Claude Sonnet 4 and DeepSeek V3 each achieved 100% recall across four evaluated malware scenarios. | Those malware scenarios and the study’s targeted retrieval setup, not malware investigations generally. |
| Cadet and coauthors (arXiv, 2026) | DeepSeek analysis cost was reported as $0.008 versus $0.12 for Claude. | The models and analysis setup evaluated in that study; this is not a general or current price comparison. |
| Cadet and coauthors (arXiv, 2026) | Attack-step detection on the evaluated Active Directory scenarios reached 100% precision and 82% recall. | The study’s Active Directory scenarios. These figures do not establish performance on other environments. |
Other evidence has narrower boundaries too. Agrawal and coauthors study coordinated attacks and incident response in a simulated cyber range using CICIDS2017 and UNSW-NB15 datasets; simulation findings are not field validation. Qiu and coauthors describe a RAG- and knowledge-graph-based response design. Microsoft’s SecRL repository describes ExCyTIn-Bench for evaluating LLM agents on cyber-threat investigation in a database environment, and points to ACESEvals as an evaluation harness. Such benchmarks measure their defined tasks, not live SOC outcomes.
These examples make the design space more concrete, but none independently verifies RECALL-X’s implementation, deployment, or improvement from incident to incident.
How to test whether the agent actually learns
Successful retrieval is not the same as better decisions. Evaluate on held-out incidents, including both cases where a prior lesson should transfer and cases where similar-looking incidents require different responses. Where feasible, compare the agent’s work with an expert-reviewed answer key or validated outcome record. Keep benchmark, simulation, retrospective, and prospective production results clearly separate.
Measure the parts of the loop separately:
- Evidence handling: timeline accuracy, indicator extraction, source coverage, and whether important gaps are disclosed.
- Retrieval: relevance of retrieved cases, provenance completeness, and whether caveats reach the operator.
- Investigation: root-cause and attack-step precision and recall, including missed critical steps.
- Response quality: usefulness and safety of recommendations, false positives, and harmful side effects.
- Operational outcomes: time to detection, containment, remediation, and recovery.
- Learning over time: whether reviewed lessons are retrieved and improve later decisions; recurrence of earlier errors; and whether corrections are incorporated.
- Operational cost: analyst review burden, system cost, and performance drift as the underlying data changes.
A credible learning claim depends on evidence that a reviewed lesson changed a later decision for the better—not simply that the system stored more incidents. Microsoft SecRL’s benchmark illustrates one way to test investigation tasks; the studies above report other task-specific measures, not a universal evaluation standard.

Incident data can contain credentials, personal or customer information, sensitive telemetry, and attacker-controlled text. Treat retrieved incident content as untrusted input rather than instructions for the agent. Minimize and redact retained data where appropriate, limit access and retention, audit reads and writes, validate tool arguments, and keep a human review trail for changes to canonical lessons or guardrails. These are recommended safeguards, not controls established as present in RECALL-X.

Require approval appropriate to the impact before disruptive containment actions. Record what the agent proposed, what an operator approved or changed, and what happened afterward. That history helps distinguish a useful lesson from an action that happened to coincide with recovery.
Best Value
Do not copy a past response without checking whether the current asset, business impact, attacker behavior, software, and legal or operational constraints match. A stale or unreviewed summary can turn an earlier mistake into a repeated one. A useful agent makes the reason for a proposed transfer visible and leaves room for the operator to reject it.
What a credible RECALL-X claim would need to establish
Calling an incident-response agent capable of learning should be backed by a traceable chain: current evidence supports the investigation; relevant prior knowledge is retrieved with provenance; a controlled recommendation or action is evaluated; and a reviewed outcome updates future behavior. Tests should show how often that loop improves decisions, how it behaves when old lessons do not apply, and what safety and operational costs it introduces.
Until those points are demonstrated for RECALL-X itself, its persistent-memory description is a design premise, not evidence of reliable learning or improved real-world response.
