12 Collaboration Tools that Most Government Agencies Prefer 

Here are our 12 shortlisted collaboration tools for government agencies, selected based on their popularity among government agencies, software quality, and ease of implementation and use.

‍

1. Microsoft Teams

Microsoft is the company behind Microsoft 365, and Teams is its flagship communication and collaboration hub. It bundles chat, video meetings, file co-authoring, and workflow automation into one platform tightly integrated with the rest of the M365 ecosystem.

‍

Collaboration tools for government:

• Teams core (chat, channels, video meetings): real-time communication across agencies and with contractors
• Power Automate integration: automates multi-step approval workflows for budget, licensing, and proposals
• Microsoft Forms/polls: built-in citizen feedback and internal employee surveys
• SharePoint/OneDrive integration: centralized document co-authoring and records management
• Azure AD-based identity and DLP/eDiscovery: supports FedRAMP, CJIS, and HIPAA compliance needs

‍

Real-world example/case study:

The City of Everett deployed Microsoft Teams to streamline communication across agencies, alongside Azure for storage and Power BI for analytics-driven decision-making. This gave city leaders greater agility across departments and helped minimize disruption to daily operations at the onset of the COVID-19 crisis, laying a foundation the city continued to build on as it grew.  (Source: Microsoft Industry Blogs)

‍

Limitation: A 2025 zero-day cyberattack targeting servers running Microsoft SharePoint reportedly impacted at least two U.S. government agencies. By gaining access to internal servers, attackers may have been able to steal sensitive data from connected Outlook and Teams accounts, including passwords and cryptographic keys. This shows that Teams' deep integration with the rest of the Microsoft stack also means a vulnerability elsewhere in that stack can expose Teams data. (Source: Yahoo News)

2. Slack

Slack is a workplace messaging and collaboration platform, and GovSlack is its dedicated instance built for the compliance needs of the U.S. federal government and the organizations that work alongside it.

‍

Collaboration tools for government:

• GovSlack: dedicated instance running in AWS GovCloud, built to support FedRAMP High, ITAR, FIPS 140-2, CJIS, and DoD IL4 requirements
• Slack Connect: secure external channels for interagency and contractor collaboration
• Channels and huddles: real-time team communication organized by project or topic
• Salesforce Government Cloud Plus integration: combines CRM and collaboration for case management and constituent services

‍

Real-world example/case study:

The U.S. Army Software Factory, which upskills soldiers in modern software development to build digital solutions for Army problems, adopted GovSlack during its beta to support nimble, secure collaboration. In its first two years, the Software Factory considered more than 100 Army problems and was developing 10 different applications to solve them, and its success with GovSlack is expected to encourage adoption elsewhere in the Army. (Source: Slack customer stories)

‍

Limitation: GSA's 18F unit, another named Slack user in government, was found by the agency's Office of Inspector General to have exposed more than 100 GSA Google Drive accounts, containing PII and contractor proprietary information, for at least five months due to an OAuth 2.0 integration between Slack and Google Drive. Neither Slack nor OAuth 2.0 were approved under GSA guidelines at the time, and the IG recommended GSA halt use of both until properly authorized.  (Source: Nextgov/FCW)

‍

3. Zoom for Government

Zoom is a video communications company, and Zoom for Government is its dedicated platform built to meet the security requirements of U.S. federal, state, and local agencies.

‍

Collaboration tools for government:

• Zoom Meetings and Chat: FedRAMP Moderate authorized video conferencing and messaging
• Zoom Phone: cloud phone system that lets agencies consolidate legacy telephony onto a single platform
• Zoom Rooms: turns government offices into managed, in-room collaborative workspaces
• Zoom AI Companion: FedRAMP JAB authorized AI features for meeting summaries and task automation
• AWS GovCloud hosting: keeps data within a secured government-specific cloud environment

‍

Real-world example/case study:

Over two dozen federal agencies use Zoom, including the Department of Defense, the Department of Homeland Security, U.S. Customs and Border Protection, and the Executive Office of the President, following Zoom's FedRAMP Moderate authorization in April 2019 under DHS sponsorship.  (Source: TechCrunch)

‍

Limitation: Senator Ron Wyden raised concerns that GSA cleared Zoom for federal use in April 2019 just weeks before security researchers discovered multiple serious vulnerabilities in the app, and criticized this as raising questions about the rigor of FedRAMP's audit process. GSA later denied Wyden's request to review the underlying security documentation. (Source: The Hill)

4. Google Workspace

Google Workspace is Google's suite of cloud productivity and collaboration tools, including Gmail, Drive, Docs, Meet, and Chat, offered in a government-focused edition with additional compliance controls.

‍

Collaboration tools for government:

• Gmail, Drive, and Docs: real-time co-authoring and centralized file storage across departments
• Google Meet and Chat: video conferencing and messaging built into the same suite
• Gemini and NotebookLM: AI-assisted drafting, summarization, and research tools included at no extra cost
• BeyondCorp zero-trust security: identity and device verification without relying on a traditional network perimeter
• FedRAMP High and DoD Impact Level 4 certifications: built for federal compliance requirements

‍

Real-world example/case study:

The U.S. Department of Transportation selected Google Workspace and Gemini as its new agency-wide collaboration suite, moving away from legacy technology providers it found outdated and costly to secure. The department's team deployed the foundational system and migrated initial users to Workspace in just 22 days. (Source: Google Cloud Blog)

‍

Limitation: In November 2025, a Google Workspace outage disrupted access to Drive, Docs, and Sheets for roughly eight and a half hours, with users encountering SSL and server connection errors. Google Drive alone serves more than 800 million daily users, so an outage of this kind can disrupt any organization, including government agencies, that depends on the suite for day-to-day document access.

5. Cisco Webex

Cisco is a networking and communications company, and Webex is its video meetings, calling, and messaging platform, offered in dedicated Webex for Government and Webex for Defense editions.

‍

Collaboration tools for government:

• Webex Meetings and Calling: FedRAMP Moderate authorized video conferencing and cloud calling
• Webex for Defense: DISA-authorized at DoD Impact Level 5 for military and defense use
• Webex Contact Center Enterprise for Government: supports up to 36,000 concurrent agents for citizen-facing services
• UCM Cloud for Government: compliant cloud-based unified communications for agencies
• U.S.-only data centers: physical infrastructure dedicated to government customers, with access restricted to U.S. persons

‍

Real-world example / case study:

With the U.S. Navy's sponsorship as required by the accrediting authority, Cisco began the process with DISA's Cloud Assessment and Authorization Division to bring Webex for Defense to DoD Impact Level 5 provisional authorization, extending the same collaboration capabilities and user experience already available through Webex for Government to the Department of Defense. (Source: Webex Blog)

‍

Limitation: In April 2026, Cisco disclosed a critical vulnerability (CVE-2026-20184, CVSS 9.8) in Webex Services affecting organizations using single sign-on integration with Control Hub. The flaw could let an unauthenticated remote attacker bypass authentication entirely and impersonate any legitimate user, gaining access to meetings, files, and private communications. Cisco said no temporary workaround existed and required affected customers to manually upload a new SAML certificate to stay protected. (Source: BleepingComputer)

Flight managers can now share flight plans and mission packages directly to aircrews' electronic flight bags about two hours before a flight, up from roughly 30 minutes previously, giving crews more time to prepare and resolve cargo or fuel issues before departure. (Source: Mattermost customer story)

‍

Limitation: Security researchers have disclosed multiple critical authentication vulnerabilities in Mattermost over the past year, including CVE-2025-12421, a flaw in the SSO code exchange process that could let an already-authenticated attacker take over another user's account, alongside earlier related flaws (CVE-2025-12419, CVE-2025-58073) in OAuth and SSO handling. Researchers noted the recurrence of authentication-related issues points to an area needing ongoing attention. (Source: ZeroPath)

‍

7. Kiteworks

Kiteworks is a secure content and file-sharing company, formerly known as Accellion, offering a Private Data Network built for organizations that need to govern and audit sensitive data exchange.

‍

Collaboration tools for government:

• Secure File Sharing: encrypted transfer of PII and sensitive records with parents, courts, and other trusted third parties
• Secure Email: encrypted email with multi-factor authentication for sensitive correspondence
• Managed File Transfer: connects to existing repositories like SharePoint, OneDrive, and SFTP servers
• Zero-trust access controls: verifies every access request and maintains continuous monitoring
• FIPS 140-3 validation and FedRAMP High readiness: built for CJIS, HIPAA, and other regulated data types

‍

Real-world example / case study:

The Texas Juvenile Justice Department, a state agency with 2,500 employees operating dozens of facilities statewide, adopted Kiteworks to comply with Texas Family Code requirements protecting highly sensitive juvenile justice information. According to the agency's Information Security Officer, Kiteworks was the only solution that met the department's strict security guidelines while remaining easy enough for nontechnical staff to use. (Source: Kiteworks case study)

‍

Limitation: Kiteworks' predecessor company, Accellion, suffered a major breach in December 2020 and January 2021 when attackers exploited zero-day vulnerabilities in its legacy File Transfer Appliance product. The breach affected government agencies among its roughly 100 victim organizations worldwide, and in Washington State, it exposed data from at least 1.6 million unemployment claims after attackers accessed files from the state's Employment Security Department and other agencies.

‍

8. Element (Matrix)

Element is a secure communications company built on Matrix, an open, decentralized protocol that lets organizations host and control their own messaging infrastructure while still federating securely with other Matrix users.

‍

Collaboration tools for government:

• Element Server Suite: enterprise-grade backend with advanced identity and access management, integrating with directories like Active Directory
• End-to-end encryption: keeps messages readable only by participants, even if a server is compromised
• Air-gapped and high-side deployments: support for isolated environments with no internet connectivity
• Cross-domain federation: lets allied or partner organizations communicate securely while each retains control of its own infrastructure
• Open source and open standard: avoids vendor lock-in and allows independent security review

‍

Real-world example/case study:

U.S. Senators Ron Wyden and Eric Schmitt sent a letter to the Department of Defense urging rapid adoption of Matrix to improve the security and sovereignty of military communications, specifically citing its successful use by the U.S. Navy and multiple NATO allies, and criticizing continued reliance on platforms like Microsoft Teams by comparison. (Source: Element blog)

‍

Limitation: A peer-reviewed forensic analysis published in a Digital Forensics Research Workshop (DFRWS) study identified practically exploitable cryptographic vulnerabilities in the Matrix protocol and Element client, including flaws that could break confidentiality guarantees through homeserver control over room membership, and impersonation risks from implementation bugs in the underlying encryption protocols. The researchers noted a broader absence of formal cryptographic analysis in Matrix and called for more systematic security evaluation of federated communication systems. (Source: ScienceDirect)

9. Signal

Signal is a nonprofit-operated, end-to-end encrypted messaging app. It is not an official government platform, but it has become a notable, if controversial, tool that some officials use informally for sensitive conversations.

‍

Collaboration tools for government:

• End-to-end encrypted messaging: ensures only participants in a conversation can read messages
• Disappearing messages: automatically deletes messages after a set time period
• Group chats: supports multi-participant conversations, similar to other messaging apps
• No message metadata retention: Signal does not store information about the messages it handles
• Cross-platform availability: works on mobile and desktop, requiring no special agency infrastructure

‍

Real-world example/case study:
‍

In March 2025, senior Trump administration officials, including the Secretary of Defense, the Vice President, the Secretary of State, and the National Security Advisor, used Signal to discuss detailed plans for military strikes against Houthi rebels in Yemen. The National Security Advisor inadvertently added The Atlantic's editor-in-chief to the group chat, who then published parts of the conversation, including operational details about strike timing and weapons systems. (Source: CNN)

‍

Limitation: Signal is end-to-end encrypted and government officials are permitted to use it for unclassified, nonsensitive conversations, but no agency has approved it for classified discussions. In the Yemen chat, one official set messages to automatically disappear after one week, which raised federal record-keeping concerns since the Presidential Records Act requires conversations of this nature to be preserved, and it remains unclear whether an official record of the conversation exists. (Source: CNN)

‍

10. Granicus

Granicus is a govtech company offering a Citizen Experience Platform that spans public meeting management, website content management, and digital communications (through its govDelivery product) built specifically for government agencies.

‍

Collaboration tools for government:

• govDelivery Digital Communications: email, SMS, and social media outreach in one platform for citizen engagement
• Meeting and legislative management: live webcasting, agenda management, and video archiving of public meetings
• Government Experience Agent (GXA): AI-driven tool letting residents self-serve for common requests
• Website content management: a CMS built specifically for government sites
• Analytics and reporting: tracks which communications and channels are driving citizen engagement

‍

Real-world example / case study:

The Oregon Department of Corrections used Granicus's data analytics tools to tailor its content and communication strategies for more effective citizen engagement. According to the department's Communications and Government Relations Manager, the agency had previously been "flying in the dark" before adopting Granicus, and being able to see where its communications were working became critical to its outreach efforts. (Source: Granicus)

‍

Limitation: The Electronic Frontier Foundation found that Granicus, which serves over 4,000 federal, state, and local agencies, continued to use HTTP for tracking links in government emails and did not support STARTTLS for in-transit email encryption on all its infrastructure, despite the company holding FedRAMP authorization. EFF concluded this fell short of the "across the board" encryption standard the certification is meant to represent. (Source: EFF)

‍

11. Tyler Technologies

Tyler Technologies is a public sector-focused software company providing integrated case management, ERP, courts, and workforce management solutions used across federal, state, and local government.
