Collaborative ConMon

Also known as: Collaborative Continuous Monitoring

Simply put

Collaborative ConMon is a FedRAMP approach in which multiple federal agencies share the responsibility of overseeing a cloud service provider's ongoing security monitoring rather than each agency reviewing it separately. It creates a common forum where agencies and the cloud provider can raise questions and reach agreement on issues such as deviation requests. The goal is to reduce duplicated effort for agencies while giving the cloud provider a coordinated point of engagement.

Formal definition

Collaborative ConMon is a model within the FedRAMP continuous monitoring (ConMon) process that establishes a collaboration group of federal agency stakeholders to jointly perform ConMon oversight of a Cloud Service Provider (CSP). Per FedRAMP legacy documentation, the model distributes ConMon oversight responsibility across participating agencies and provides a central forum to review recurring ConMon deliverables and to reach consensus on matters such as deviation requests. Governance is organized through mechanisms including a group charter agreed to at an inaugural meeting, with recurring collaboration meetings; RFC-0016 discussion referenced a transition of these meetings from monthly to quarterly cadence, indicating the standard is evolving and readers should verify the current authoritative FedRAMP text. This model addresses the shared review of ConMon evidence (for example vulnerability scans and other required deliverables submitted under the broader ConMon process) but does not itself confer or replace an Authority to Operate (ATO), which remains time-bound and subject to continuous monitoring; nor does it substitute for each authorizing official's independent authorization decision. Specific procedural details, meeting cadence, and applicable revisions should be confirmed against current official FedRAMP sources.

Why it matters

Under the traditional FedRAMP model, when a single cloud service provider (CSP) holds authorizations across multiple federal agencies, each agency may independently review the same continuous monitoring deliverables, vulnerability scans, deviation requests, and other recurring evidence. This creates duplicated effort across the government and gives the CSP multiple, sometimes inconsistent, points of engagement to satisfy. Collaborative ConMon matters because it distributes ConMon oversight responsibility across participating agencies and establishes a common forum where questions can be raised and consensus reached on issues such as deviation requests, reducing redundant review while giving the CSP a coordinated interface.

For compliance officers and authorizing officials, the model is significant precisely because it changes how oversight is organized without changing the underlying accountability. Sharing review responsibility does not dissolve any individual authorizing official's independent authorization decision, and participation in a collaboration group does not confer or replace an Authority to Operate (ATO). An ATO remains time-bound and subject to continuous monitoring regardless of whether oversight is conducted collaboratively or agency-by-agency. Practitioners should be careful not to treat consensus reached within a collaboration group as a substitute for their own agency's authorization responsibilities.

The model is also evolving. Community discussion referenced in RFC-0016 noted a transition of collaboration meetings from a monthly to a quarterly cadence, described as an improvement intended to enhance the value of these meetings. Because governance mechanisms and cadence are subject to change, readers should verify current meeting cadence, procedural details, and applicable revisions against current official FedRAMP sources rather than relying on any single point-in-time description.

Who it's relevant to

Federal Agency Authorizing Officials and ISSMs

Agencies that share a common CSP can use Collaborative ConMon to distribute oversight responsibility and reduce duplicated review effort. However, participation does not replace an individual authorizing official's independent authorization decision, and consensus reached in the collaboration group does not substitute for each agency's own accountability. An ATO remains time-bound and subject to continuous monitoring.

Cloud Service Providers (CSPs)

CSPs benefit from a coordinated point of engagement rather than fielding separate, potentially inconsistent reviews from each authorizing agency. The central forum lets the CSP raise questions and reach consensus on issues such as deviation requests, but it does not change the underlying obligation to submit required ConMon deliverables such as vulnerability scans.

Compliance Officers and Auditors

Those tracking FedRAMP continuous monitoring should understand how oversight is governed under this model, through a group charter agreed at an inaugural meeting and recurring collaboration meetings. Because meeting cadence and procedures are evolving (for example, the referenced monthly-to-quarterly transition), auditors should verify current requirements against official FedRAMP sources and confirm that assessment and review activity is not being conflated with formal authorization.

Inside Collaborative ConMon

Continuous Monitoring (ConMon)

The ongoing process of maintaining awareness of an information system's security posture, vulnerabilities, and threats to support risk-based decisions after an authorization is granted. In FedRAMP and RMF contexts, ConMon generally includes recurring vulnerability scanning, configuration management, incident reporting, and periodic reporting to the authorizing party. Specific cadences and deliverables vary by program, impact level, and the applicable revision of governing guidance, and should be verified against current official sources.

Collaborative Element

The aspect that distinguishes 'Collaborative ConMon' from single-party monitoring: multiple stakeholders (for example a cloud service provider, a leveraging agency, and, in FedRAMP, the FedRAMP PMO or a Joint Authorization Board where applicable) share monitoring data, findings, and remediation status. This generally reduces duplicated effort when one authorization is reused across multiple consumers, though roles and responsibilities differ by program.

Shared Responsibility Allocation

A defined division of monitoring and remediation duties among the parties, typically documented so each party understands which controls, scan scopes, and reporting obligations it owns. This is closely tied to but distinct from the shared responsibility model for security control implementation; the reader should confirm allocations against the applicable contract, System Security Plan, and program guidance.

Deliverables and Reporting Artifacts

Recurring outputs that support collaborative review, which in most implementations include vulnerability scan results, a Plan of Action and Milestones (POA&M), and inventory or configuration updates. The exact required artifacts, formats, and frequencies depend on the governing program and its current revision and are not fixed by this entry.

Authorization Linkage

ConMon activities sustain an existing authorization decision (such as an ATO) rather than granting one. Collaborative ConMon supports the authorizing official's ongoing determination that residual risk remains acceptable; assessment and reporting activities feed, but do not replace, the authorization decision.

Common questions

Answers to the questions practitioners most commonly ask about Collaborative ConMon.

Does an initial FedRAMP authorization or ATO mean continuous monitoring obligations are satisfied?

No. An authorization is time-bound and conditioned on ongoing continuous monitoring (ConMon). Collaborative ConMon arrangements are premised on the understanding that an ATO is not permanent; the authorizing official's acceptance of risk depends on the continued receipt and review of monitoring deliverables. Failure to sustain ConMon can jeopardize the authorization. Readers should verify specific ConMon deliverable expectations against current FedRAMP PMO guidance and their agency's terms.

If continuous monitoring shows a system is compliant, does that mean it is secure?

Not necessarily. Compliance and security are distinct. Collaborative ConMon demonstrates that agreed monitoring activities are being performed and that reporting obligations are being met, but meeting reporting cadence and control checks does not by itself guarantee that a system is free of exploitable risk. Compliance evidence should be treated as one input to a risk determination rather than as proof of security.

How is monitoring responsibility typically divided among the parties in a Collaborative ConMon arrangement?

In most implementations, responsibilities are allocated among the cloud service provider or system owner, the authorizing official or leveraging agencies, and any coordinating body, with each party responsible for defined deliverables, reviews, and communications. The specific division depends on the arrangement's governing documentation. Readers should confirm the exact allocation of duties against the applicable agreement and current authoritative guidance, since roles vary by program and revision.

What deliverables are generally expected as part of a Collaborative ConMon process?

Continuous monitoring processes generally involve recurring deliverables such as updated plans of action and milestones, vulnerability or scan reporting, and change notifications, submitted on an agreed cadence. The precise set, format, and frequency of deliverables are defined by the governing program and can change across revisions, so readers should verify current requirements against the applicable official ConMon guidance rather than assume a fixed list.

How should agencies leveraging a shared authorization approach their ConMon responsibilities?

Leveraging agencies generally retain responsibility for reviewing monitoring outputs and making their own risk determinations, even where monitoring activities are coordinated collaboratively. A shared or collaborative arrangement does not transfer the leveraging authorizing official's accountability for accepting residual risk. Agencies should confirm their specific review and acceptance obligations against the arrangement's terms and current guidance.

What should be documented to establish a Collaborative ConMon arrangement?

Arrangements are generally documented so that the scope, roles, deliverables, cadence, and escalation or communication procedures are clear to all participants. Because the required documentation and its structure depend on the governing program and may evolve across revisions, readers should verify the current documentation expectations against the applicable authoritative sources rather than rely on a generic template.

Common misconceptions

An authorization obtained with a collaborative ConMon program is permanent and does not need revisiting.

An ATO is time-bound and conditional on sustained continuous monitoring. Collaborative ConMon exists precisely because the authorizing party must maintain ongoing awareness; failure to meet monitoring and remediation obligations can jeopardize the authorization. Verify the specific conditions and duration in the applicable authorization letter and program guidance.

Because monitoring is shared, a FedRAMP-authorized service with collaborative ConMon automatically satisfies DoD monitoring requirements.

FedRAMP authorization and its associated monitoring do not automatically satisfy DoD requirements. DoD systems handling CUI or operating under the RMF may impose additional or different monitoring, impact-level, and reporting obligations. Each consuming party must independently confirm that the collaborative ConMon outputs meet its own governing requirements.

Participating in collaborative ConMon means the system is secure.

Compliance with a monitoring process is not the same as being secure. Collaborative ConMon provides visibility and supports risk decisions, but it does not by itself eliminate vulnerabilities or guarantee an acceptable security posture; findings must still be assessed and remediated on a risk basis.

Best practices

Document the division of monitoring and remediation responsibilities among all participating parties in writing, and reconcile it against the System Security Plan, contract, and applicable program guidance before relying on shared data.

Treat the underlying authorization as time-bound and condition-dependent, and track the specific monitoring cadences and deliverables required to keep it valid under the applicable revision of governing guidance.

Independently verify that shared ConMon outputs meet your own organization's governing requirements rather than assuming another party's authorization or monitoring satisfies them.

Maintain and regularly update a POA&M and inventory so that shared findings reflect current remediation status, and confirm required formats and frequencies against current official sources.

Distinguish assessment and reporting activities from the authorization decision, ensuring the authorizing official retains and exercises the risk-acceptance role based on collaborative monitoring inputs.

Re-verify program requirements against the current authoritative text periodically, since baselines, impact levels, and reporting obligations can change across revisions and agency tailoring.
