Every few years, someone declares fax machines dead. The same people tend to roll their eyes at EDI and wonder aloud why eDiscovery software costs so much. And every few years, those technologies quietly keep running, processing millions of documents a day for industries that cannot afford to get compliance wrong.
The truth is not that these tools have failed to evolve. It is that the industries using them, legal, healthcare, and logistics, operate under constraints that make "just switch to email" a dangerously naive suggestion. If your business touches any of these sectors, understanding why this software persists is not nostalgia. It is practical buying intelligence.
Fax Is Not Dead. It Moved to the Cloud.
Approximately 70% of healthcare providers still use fax to exchange medical information. That number jumps closer to 90% when you include faxes flowing through EHR systems. In legal offices, faxed documents remain admissible proof of delivery in ways that email attachments often are not. The reason is straightforward: HIPAA, SOX, and various state bar regulations treat fax transmissions as inherently more secure and auditable than standard email.
What has changed is the hardware. Analog fax lines are being phased out under FCC Order 19-72A1, which required legacy analog telephone service lines to be retired starting in 2025. That does not mean faxing is going away. It means the fax machine on the counter is being replaced by cloud fax software that sends and receives through encrypted digital channels while maintaining the compliance paper trail that regulators demand.
The new federal HTI-4 rule, effective October 2025, pushes healthcare IT systems toward real-time data exchange and reduced fax reliance. But "reduced" is doing a lot of heavy lifting in that sentence. Interoperability gaps between different EHR systems mean that fax remains the universal fallback, the one format every clinic, hospital, and insurance office can send and receive without worrying about system compatibility.
For buyers evaluating fax software on Serchen, the key criteria are HIPAA compliance (including a signed Business Associate Agreement), end-to-end encryption, audit trails, and integration with existing EHR or practice management systems.
Vendors worth knowing
iFax is one of the more feature-rich options in the cloud fax space. It offers HIPAA-compliant faxing with 256-bit SSL encryption, team collaboration tools, API integrations, and compatibility with major EHR/EMR platforms. Pricing starts at around $12.49 per month for a basic plan, with the HIPAA-compliant tier at $24.99 per month. The platform serves over 20,000 companies and supports iOS, Android, Mac, Windows, and web. The main criticism from users is that the free tier is limited and the HIPAA toggle in the send flow is not enabled by default, which requires some attention during setup.
eFax is one of the oldest and largest internet fax providers. It built its reputation on simplicity: faxes arrive as email attachments, and sending works the same way in reverse. For organizations that need a proven, low-friction migration from physical fax machines, eFax remains a safe starting point. It lacks some of the deeper healthcare workflow integrations that newer competitors offer, but its brand recognition and reliability keep it relevant.
Concord Technologies focuses specifically on enterprise and healthcare fax. Its Concord Cloud Fax platform is built for organizations where regulatory compliance is not optional. The platform includes NEXTSTEP, a workflow automation layer that routes incoming faxes to the right department or system automatically. If your fax volume is high and your compliance requirements are strict, Concord is designed for exactly that scenario.
Fax.Plus positions itself as a cross-platform fax solution trusted by over two million users. It is straightforward, secure, and works across devices. For smaller legal practices or clinics that need reliable cloud fax without a complex enterprise deployment, Fax.Plus is a clean option.
EDI: The Invisible Backbone of Logistics
If fax is the technology that everyone sees and questions, EDI is the one that nobody sees and nobody questions, until it breaks. Electronic Data Interchange automates the exchange of purchase orders, invoices, advance shipping notices, and other standardized business documents between trading partners. It has been doing this since the 1970s.
The reason EDI persists in logistics and supply chain management is not inertia. It is that no alternative matches its combination of standardization, speed, and universal acceptance among trading partners. Major retailers, distributors, and manufacturers require EDI compliance from their suppliers. If you sell to Walmart, Target, or Amazon as a wholesale vendor, you are using EDI whether you planned to or not.
Modern EDI software has moved well beyond flat-file translations. Today's platforms offer cloud-native deployment, real-time dashboards, API connectivity, and integration with ERP, WMS, and CRM systems. The shift to cloud-based EDI has made onboarding new trading partners faster and reduced the need for dedicated in-house EDI specialists, though the learning curve for more complex implementations remains real.
According to IBM, EDI automates document exchange to cut transaction times from days to minutes, reduces human error from manual data entry, and saves on paper, postage, and labor costs. For logistics operations running on thin margins, those savings are not theoretical. They are the difference between a profitable quarter and a missed one.

Boomi is a heavyweight in the integration platform space, and its B2B/EDI management module brings that enterprise muscle to supply chain document exchange. Boomi's strength is that EDI is not a standalone product but part of a broader integration, automation, and AI platform. That means you can connect EDI transactions directly to your ERP, automate downstream workflows, and use dashboards for real-time visibility. Pricing is connector-based and scales with volume, with most mid-sized businesses spending between $25K and $75K annually. That is not cheap, but for organizations managing dozens of trading partners, the consolidation value is significant.
Cleo offers the Cleo Integration Cloud, a platform purpose-built for ecosystem integration across EDI, non-EDI, and API connections. Its focus on end-to-end visibility makes it popular with logistics companies that need to see the full picture of what is moving, where, and when. Cleo is particularly strong for mid-market companies that have outgrown basic EDI translation tools but do not need the full complexity of an enterprise iPaaS deployment.
CData Arc (formerly known as Arc) takes a different approach, packaging EDI processing with managed file transfer and back-office integration in a single platform. It connects to CRMs, ERPs, marketing, and accounting software, making it a good fit for companies that want EDI as part of a broader connectivity strategy without stitching together multiple vendors.
1 EDI Source has been in the EDI business for over 30 years, offering both cloud-based and managed solutions. For companies that want a dedicated EDI provider rather than a feature inside a larger platform, 1 EDI Source provides deep specialization and a track record across industries from retail to manufacturing.
eDiscovery: Growing Faster Than Anyone Expected
Electronic discovery is the process of identifying, collecting, and producing electronically stored information (ESI) in response to legal requests. Unlike fax and EDI, which are often seen as legacy holdovers, eDiscovery is unmistakably modern. The global market was valued at nearly $15 billion in 2023 and is projected to reach over $31 billion by 2030, growing at roughly 10.7% annually.
The driver is not just more lawsuits. It is more data. Every Slack message, Teams chat, email thread, cloud document, and AI-generated summary is potentially discoverable in litigation. The volume of ESI that legal teams must process has grown exponentially, and the tools required to handle it have become correspondingly sophisticated. AI-powered document review, predictive coding, and automated privilege detection are now standard features, not premium add-ons.
For corporations, law firms, and government agencies, the question is no longer whether to invest in eDiscovery software. It is which platform can handle the scale and complexity without blowing up the budget. Cloud adoption has become the norm, with 66% of organizations now running eDiscovery in the cloud according to the 2025 Ediscovery Innovation Report.
Vendors worth knowing
Relativity is the market leader and the name most legal professionals associate with eDiscovery. Its RelativityOne cloud platform handles everything from data collection and processing to AI-powered review and production. It supports modern data types including Slack messages, Teams chats, and AI-generated content, with built-in translation for over 100 languages. Relativity was named a Leader in the 2025 IDC MarketScape for end-to-end eDiscovery. Pricing is custom and typically volume-based, with pay-as-you-go rates generally in the $7 to $14 per GB range.
Everlaw has built a strong reputation as a modern, cloud-native alternative. Its platform emphasizes ease of use and collaborative review, making it popular with both large law firms and in-house legal teams. Everlaw publishes its own annual Innovation Report tracking industry trends, and its pricing, while also custom, is generally seen as competitive with Relativity for mid-sized matters.
Logikcull (now part of Relativity) made its name by simplifying eDiscovery for smaller legal teams and corporate legal departments. Its drag-and-drop upload and automated processing model removed much of the technical overhead that historically made eDiscovery expensive and specialist-dependent. For organizations handling routine litigation or internal investigations, Logikcull offers a more accessible entry point.
Casepoint targets large corporations and government agencies with an end-to-end platform that combines AI, advanced analytics, and data collection from diverse sources. It is particularly well regarded in the federal government space, where data sensitivity and chain-of-custody requirements add extra layers of complexity.
What Buyers Should Actually Care About
The common thread across fax software, EDI, and eDiscovery is compliance. These are not glamorous tools. They do not generate viral demos or trend on social media. What they do is keep organizations on the right side of HIPAA, FDA, SEC, and Federal Rules of Civil Procedure requirements. When evaluating any of these categories, the buying criteria that matter most are:
- Regulatory compliance. Does the platform meet the specific standards your industry requires? For fax, that means HIPAA and signed BAAs. For EDI, that means support for the document standards your trading partners mandate. For eDiscovery, that means defensible workflows and audit trails.
- Integration. How well does the tool connect to your existing systems? A fax platform that does not talk to your EHR is a step backward. An EDI solution that cannot sync with your ERP creates more work than it saves.
- Scalability. Volume matters in all three categories. Make sure pricing and performance hold up as your document counts grow.
- Security. End-to-end encryption, role-based access, and detailed logging are table stakes, not nice-to-haves.
Next Steps
These three categories are not going anywhere soon. If anything, tightening regulations and growing data volumes are making them more essential, not less. The real question for buyers is not "should we use this?" but "which platform fits our workflow and compliance needs best?"
