In an industry where data protection is non-negotiable, the actual cost of outdated legacy systems extends beyond IT maintenance budgets.
As Matt Murren, CEO of True North ITG, puts it, “I’ve seen firsthand how legacy email platforms can quietly—but critically—undermine operational stability and efficiency across healthcare organizations.” He further warns that “outdated systems often lack the security frameworks, integration capabilities, and scalability that modern healthcare environments demand. … This translates into a number of recurring issues, including frequent downtime, inefficient workflows, security vulnerabilities, and compliance risks.”
In the article Transitions from One Electronic Health Record to Another: Challenges, Pitfalls, and Recommendations, legacy systems are described in the context of electronic health record (EHR) transitions.
According to the authors, legacy systems refer to: “Older electronic health record (EHR) systems that have been in use for many years and contain large amounts of clinical and administrative data accumulated over time.”
They further note that these systems often:
In the context of email, a legacy email system may be characterized by one or more of the following:
The article Modernizing for Growth: Overcoming the Hidden Costs of Legacy Systems offers a clear lens through which to view the often-overlooked burdens that legacy infrastructure places on organizations. While the piece is written with a broad enterprise audience in mind, its insights are highly transferable to healthcare settings, especially when applied to email systems that support protected health information (PHI), care coordination, and compliance workflows.
Here are the key themes from the report:
The report notes that “nearly two-thirds of companies spend more than $2 million annually on maintaining legacy systems.” In a healthcare organization, this translates to large portions of the IT or communications budget being tied up in simply keeping an outdated email system running, leaving less room for innovation in patient-facing communications, secure messaging, or system integrations.
According to the article, “Legacy systems … can also create inefficiencies that hinder productivity. Many struggle to integrate with modern applications, forcing companies to rely on costly middleware or manual processes.”
In the healthcare email context, this might look like staff manually copying emails into patient records, toggling between systems to send encrypted messages, or experiencing delays when attaching lab reports. Those extra minutes per user accumulate into a significant hidden cost.
The article continues to state that “As businesses grow, legacy systems become a bottleneck … Frequent system crashes lead to costly downtime, disrupting daily operations.”
For a hospital, clinic, or health system email platform, this means growth may strain outdated systems, causing delays, outages, or degraded service. This could impact patient safety, referral timeliness, or regulatory reporting.
The report stresses this dual cost: “Security risks also increase, as older systems can lack modern threat protection, making them vulnerable to cyberattacks.”
Given that emails in healthcare often contain PHI, vendor communications, lab results, and patient correspondence, the exposure rises dramatically if the underlying system is legacy. Encryption may be insufficient, audit logs may be weak or nonexistent, and patches may no longer be supported.
The article observes that “Legacy systems represent a significant roadblock to digital transformation, creating inefficiencies, security risks, and financial burdens for businesses.”
Transposed into healthcare: when your email system cannot scale, cannot integrate with EHRs/portals, or fails to support encryption workflows, you lose the opportunity to leverage secure onboarding emails, patient engagement via email, analytics on communication flows, or seamless vendor/patient interaction. Those lost opportunities are hidden costs.
Putting it all together: maintenance costs, productivity loss, downtime risk, security/compliance exposure, and missed innovation result in a far greater total cost than the “license fee” or “server cost” alone. The RTInsights article states: “The cost of maintaining outdated technology often outweighs the investment required to modernize.”
In healthcare terms, staying on a legacy email system may appear cheaper up front, but when you factor in slower workflows, compliance risk, potential breaches, later migration burdens, patient-care delays, and staff unhappiness, the hidden cost is high.

While many healthcare organizations focus on replacing outdated EHR or record management systems, email infrastructure often remains a neglected legacy component. Traditional email servers and on-premises systems lack the encryption, interoperability, and automation capabilities required for today’s digital healthcare environment. This is where Paubox provides a modern, compliant alternative.
Paubox Email Suite enables healthcare organizations to transition from legacy email systems to a fully HIPAA compliant email platform without disrupting workflows. Unlike older systems that rely on patient portals or require recipients to log in to view encrypted messages, Paubox delivers automatic encryption directly to the inbox, ensuring secure and frictionless communication.
Key benefits during modernization include:

Legacy systems pose significant cybersecurity and compliance risks. They often lack modern encryption, two-factor authentication (2FA), and secure data storage features, making them vulnerable to breaches. They also make it difficult to comply with HIPAA and other data protection regulations.
Yes. If an outdated email system fails to properly encrypt protected health information (PHI) or lacks access controls, it can result in unauthorized disclosures. Such incidents may trigger HIPAA violations, leading to hefty fines, audits, and reputational damage.
Modern cloud-based and HIPAA compliant email systems, like Paubox, offer robust encryption, seamless integration with EHRs and scheduling systems, and improved uptime reliability. They support automation, remote access, and enhanced threat protection, leading to safer, faster, and more compliant communication.
Secure and reliable communication builds patient confidence. When patients know their information is handled safely and communication is timely, it enhances trust and strengthens relationships with providers. Conversely, a single data breach can significantly erode that trust.
