Mandiant has been a category leader for incident response and threat intelligence since 2004. Qtonic Quantum is opening a different lane: post-quantum migration evidence anchored to a 2029-01-01 readiness control date (Qtonic Quantum's target, ahead of the NIST IR 8547 (initial public draft) timeline of deprecate-after-2030 / disallow-after-2035). This page explains the fork, not a feature fight.
An enterprise security buyer might engage both. They answer different questions, on different timelines, with different artifacts.
Incident response. Threat intelligence. Red team and adversary emulation. These are the three domains where Mandiant has set the public standard for more than two decades.
Incident Response
Containment, eradication, and forensics for active or recent intrusions. The work that happens when something has already gone wrong, or is going wrong right now.
Threat Intelligence
Tracking named adversaries, their tooling, and their campaigns. Producing the briefings that make a board understand who, why, and how, with attribution.
Red Team
Adversary emulation against existing defenses. Pressure-tests detection, response, and the human side of the security organization.
Qtonic Quantum does not work in any of these three domains. We do not run incident response. We do not publish named-actor threat intelligence. We do not perform red-team engagements against classical defenses. When an enterprise needs that work done well, the established category leaders, Mandiant chief among them, are the right call.
Post-quantum migration evidence. The discipline of producing a verifiable record that the cryptography in production today is moving toward the algorithms a board will be required to attest to on the morning of 2029-01-01.
Cryptographic Inventory
Where, exactly, RSA, ECDSA, and other quantum-vulnerable algorithms are in production. Not a guess. Not a template. An evidence-graded record produced by QScout, with the scan parameters captured for replay.
Migration Evidence
A signed, replay-verifiable record that an organization is on the documented path from classical cryptography to NIST PQC standards. Not a status memo. A signature anyone can check.
This is a category that did not exist when Mandiant was founded. The NIST post-quantum standards finalized in 2024 created the regulatory clock that defines it. The 2029-01-01 readiness control date — Qtonic Quantum's target — is what gives it shape.
Not a feature fight. A use-case fork. Read the question on the left; the right answer is on the right.
The question
We have an active intrusion. Who did it, what did they take, and how do we contain it?
The right lane
An incident response retainer with a category leader such as Mandiant. Qtonic Quantum is not in this lane.
The question
Our board wants a briefing on a named adversary group targeting our sector this quarter.
The right lane
A threat intelligence subscription from a recognized provider. Qtonic Quantum is not in this lane.
The question
We need to pressure-test our detection-and-response program against a skilled human adversary.
The right lane
A scoped red-team engagement. Qtonic Quantum is not in this lane.
The question
Where, exactly, is quantum-vulnerable cryptography in our production estate, and what evidence can we hand a regulator?
The right lane
Qtonic Quantum. QScout produces the cryptographic inventory; QStrike produces the verifiable record.
The question
On 2029-01-01, can we produce a signed artifact that proves we were on the documented PQC migration path?
The right lane
Qtonic Quantum. The record is replay-verifiable and cryptographically signed.
Most large enterprises will see at least one question on the first list and at least one on the second. The categories are additive, not substitutable.
Most security vendors, across categories, generate a report. The report is a narrative. It is read, filed, sometimes forwarded. It is not, on its own, a verifiable record.
The standard pattern
The Qtonic Quantum pattern
This is not a claim that other vendors are doing the wrong work. Incident response, threat intelligence, and red-team work do not need a governed evidence record to be useful. The receipts pattern is specifically valuable when the work product is a long-lived attestation, exactly what a PQC migration record is.
The reason this category is opening now, and not five years ago, is the public NIST PQC milestone calendar.
An incident response retainer does not become more or less relevant on 2029-01-01. A signed cryptographic-inventory record does. That date is the asymmetry that defines the category.
