Best Archiving Tools for Compliance Teams (2026)

Regulatory exams have a way of surfacing gaps you didn't know you had. For a lot of firms, those gaps show up in communications archiving: a channel that wasn't captured, a record that couldn't be produced quickly enough, or a supervision workflow that flagged everything and surfaced nothing useful. Here's a look at which solutions hold up and where they fall short.

TLDR:

• SEC Rule 17a-4, FINRA Rule 4511, and the Investment Advisers Act require tamper-proof, retrievable records across all channels.
• Coverage gaps (SMS, social media, video) are among the most common deficiencies cited in regulatory exams, per the SEC Division of Examinations 2024 Priorities.
• MirrorWeb, Global Relay, and Archive Intel each cover select channels but don't connect archiving to a broader compliance program.
• Greenboard archives across 13+ channels, including YouTube, with AI supervision that reads context instead of matching keywords.

What is communications archiving?

Communications archiving is the practice of capturing, storing, and making retrievable every business-related message your firm sends or receives. For financial services firms, this covers far more than email. Text messages, instant messages, social media, video calls, voice recordings, and collaboration tools like Slack or Microsoft Teams all fall within scope depending on your firm type and regulatory obligations.

The regulatory basis runs across several rules. SEC Rule 17a-4 governs broker-dealers and sets specific requirements for how records must be stored, including write-once, read-many (WORM) format and the ability to produce records promptly for regulators. FINRA Rule 4511 builds on this with its own recordkeeping requirements. RIAs fall under the Investment Advisers Act of 1940, which requires firms to retain books and records in a way that supports regulatory examination. The common thread across all of them: records must be complete, tamper-proof, and accessible.

What counts as a communication you need to archive? Generally, anything related to the business of the firm, including:

• Client-facing emails and replies
• Text messages and iMessages sent on business or personal devices used for work
• Slack, Teams, and other collaboration tools
• Social media posts and direct messages on LinkedIn, Instagram, or WhatsApp
• Video content published publicly, like YouTube
• Voice and video call recordings where required

Gaps in coverage are among the most common deficiencies cited during regulatory exams and investigations, making a solid communications archive the foundation of any sound compliance program.

How we ranked these solutions

We reviewed each solution based on what actually matters to compliance teams at financial services firms. A note on methodology: this list reflects our perspective on what good archiving looks like, not an independent third-party audit.

The criteria we weighted:

• Channel breadth: email, SMS, iMessage, Slack, Teams, social media, video, and voice
• Regulatory posture: 17a-4 compliance, WORM storage, SOC 2 Type 2 certification
• Supervision quality: contextual AI flagging vs. keyword-based lexicon matching
• Integration depth: custodial feeds, brokerage accounts, collaboration tools
• Supervision workflows: review queues, escalation paths, audit trails
• Scalability: whether compliance overhead grows linearly with headcount or flattens over time
• Scope: standalone archiving point solution vs. part of a broader compliance operating system

That last criterion matters more than it might seem. Archiving data that sits in a silo has limited value compared to integrated compliance tooling. When it connects to supervision, marketing review, and employee compliance, it becomes actionable.

Best overall communications archiving: Greenboard

Greenboard captures the broadest channel set of any solution on this list: email, Slack, Microsoft Teams, SMS, iMessage, LinkedIn, WhatsApp, Telegram, Instagram, Facebook, Instant Bloomberg, Zoom Phone texts, and YouTube. YouTube archiving launched in 2025, making Greenboard one of the few vendors that can archive video content published to a firm's public channels.

The archive is 17a-4 and WORM compliant, SOC 2 Type 2 certified, and built for forensic search and retrieval. Records are tamper-proof, promptly producible, and defensible when regulators come knocking.

Where Greenboard separates from the field is supervision. The AI reads and contextualizes full conversations instead of scanning for keywords. A message containing the word "guarantee" in a clearly innocuous context won't surface as an alert. JMG Financial Group's CCO, Adam Boyer, put it plainly:

"Compared to our old provider, there's solid time savings in those eComms reviews week over week. We don't get nearly as many because there aren't as many false flags."

Archived data flows directly into marketing review, trade surveillance, employee compliance, and firm compliance. No separate logins, no exporting records into another tool. GreenboardGo, our plain-language chat interface, lets compliance staff query archived communications directly without needing to know search syntax. Archiving here is the data foundation of the compliance program, not a records repository running in parallel to it.

MirrorWeb

MirrorWeb is a UK-based archiving provider focused on web and social media capture for compliance-driven industries. Their core strength is defensible records of public-facing digital content.

Here's what they cover:

• Website archiving with tamper-proof records of public web pages
• Social media capture across LinkedIn, Twitter/X, and Facebook
• Email archiving with compliance-grade retention
• Regulatory reporting and audit trail support

Good for firms whose primary need is website and social media archiving, particularly those in compliance-driven industries outside of US financial markets.

The limitation is scope. Firms that need integrated supervision workflows, AI-assisted review, or a compliance program connecting archiving to trade surveillance and marketing review will find gaps.

MirrorWeb handles web and social archiving well, but its public materials describe a narrower scope. For a closer look at the differences, see our comparison with MirrorWeb. For firms that want archived data to feed into a broader compliance program, a standalone archiving tool tends to recreate the fragmentation it was meant to solve.

Global Relay

Global Relay is one of the longer-standing names in financial services archiving, with a strong foothold among broker-dealers and large financial institutions. Their core product is enterprise-grade message archiving with compliance-grade retention and search.

What they offer

• Email, instant messaging, and social media archiving for compliance-driven industries
• Supervision and review workflows with flagging and escalation tools
• Compliance reporting and audit trail documentation
• Integration with enterprise communication tools common in large institutions

Good for: Large broker-dealers or enterprise financial institutions with dedicated compliance teams and a primary need for archiving at scale.

Limitation: Global Relay functions largely as a specialized archiving and supervision product. Firms looking for marketing review, trade surveillance, vendor due diligence, or employee compliance workflows built into the same system will need to source those separately.

Channel coverage and pricing details are available directly from Global Relay.

Our comparison with Global Relay shows it does archiving well at enterprise scale, but the compliance program still has to be assembled around it. Greenboard combines archiving, AI supervision, marketing review, and employee compliance under one roof, so archived data feeds directly into the rest of the program.

Archive Intel

Archive Intel is a US-based archiving provider built for financial services firms, with a focus on social media and digital communications capture for broker-dealers and RIAs.

Their public website lists the following capabilities:

• Social media archiving across LinkedIn, Facebook, Twitter/X, and Instagram
• Email and text message capture with compliance-grade retention
• Supervision and review workflows with flagging tools
• Regulatory audit trail and reporting support

Archive Intel is a reasonable fit for smaller broker-dealers or RIAs with straightforward channel coverage needs. Where it runs short is scope: firms looking for AI-powered contextual review, marketing compliance, trade surveillance, or a unified employee compliance program will need separate tools to fill those gaps. For firms that want archived communications feeding directly into supervision, marketing review, and trade monitoring, a standalone archiving tool adds another integration to manage, not fewer.

Feature comparison table of communications archiving solutions

The table below summarizes how each solution compares across the capabilities that matter most for financial services compliance programs. Competitor columns reflect only what their public websites and the descriptions in this article support. Where a capability isn't documented publicly, the entry reads "Unknown."

A few notes on the "Partial" entries: Global Relay offers supervision workflows with flagging tools, but those workflows are not AI-driven in the contextual sense that Greenboard's are. Social media coverage across MirrorWeb, Global Relay, and Archive Intel varies by channel and does not include YouTube.

Why Greenboard is the best communications archiving solution

Archiving records is the baseline. What separates a defensible compliance program from a fragile one is what happens to those records after they're captured. Firms that archive into a silo still have to manage supervision, marketing review, trade monitoring, employee compliance, and risk assessment through separate tools, which means more vendors, more integrations, and more places for things to break before an exam.

Greenboard is the only solution in this comparison where archived communications feed directly into every other part of the compliance program. The AI supervision layer reduces false positives so your team spends time on real issues, and as JMG Financial Group found, compliance overhead doesn't scale linearly with headcount when the system is doing the first pass. According to the Root Financial case study, a small RIA team reclaimed an estimated 24 hours per week on marketing review—time their advisers were previously spending on manual compliance workflows. That's what archiving looks like when it's the foundation of the program, not a records drawer.

Final thoughts on choosing eComms archiving software

The right archiving solution captures everything and makes it searchable. The better question is whether it does anything useful after that. If your archived records sit in a separate tool disconnected from supervision and marketing review, you still have a fragmented compliance program. That is the gap worth closing before your next exam.

FAQ

How do I choose between Greenboard, Global Relay, MirrorWeb, and Archive Intel for my firm's archiving needs?

Start with scope: if you need archived communications to feed into supervision, marketing review, and employee compliance, you need a unified system, not a standalone archiving tool. If your primary need is web and social capture or enterprise-scale message retention only, MirrorWeb or Global Relay may cover that narrower use case.

Is Global Relay a better fit than Greenboard for large broker-dealers?

Global Relay is a strong choice for enterprise-scale message archiving, but it functions as a specialized archiving and supervision product. Broker-dealers that also need marketing review, trade surveillance, and employee compliance workflows built into the same system will still have to source those separately with Global Relay.

What is the difference between AI contextual supervision and lexicon-based supervision in communications archiving?

Lexicon-based supervision flags messages containing specific keywords regardless of context, which generates high false-positive rates. Contextual AI reads full conversations to assess meaning, so a word like "guarantee" in a clearly benign exchange won't trigger a review queue alert.

When should an RIA or broker-dealer consider replacing a standalone archiving tool with a unified compliance system?

If your team is managing separate logins and integrations for archiving, marketing review, and trade monitoring, the fragmentation itself becomes a compliance risk. A unified system is worth considering when your archiving data sits in a silo disconnected from the rest of your compliance program.

Does communications archiving software need to be 17a-4 and WORM compliant for SEC-registered firms?

Yes. SEC Rule 17a-4 requires broker-dealers to store records in WORM format with the ability to produce them promptly for regulators. RIAs operate under the Investment Advisers Act of 1940, which carries similar accessibility and tamper-proof requirements. Any archiving solution you select should document its compliance with these standards explicitly.
