DigiCert posts record Q4 ARR after expansion spree

DigiCert recorded its largest fourth quarter for annual recurring revenue in fiscal 2026, capping a year of product expansion and acquisitions.

The cybersecurity and digital trust supplier said fourth-quarter performance exceeded its bookings target, though it did not disclose a revenue figure. It attributed the result to demand from organisations managing shorter certificate lifespans, more complex digital systems, and growing pressure to automate certificate management.

DigiCert also used the update to highlight changes to its core DigiCert ONE platform during the year. A key step was the integration of UltraDNS, bringing public key infrastructure and domain name system management into a single system.

The move reflects a broader shift in the security market, as companies try to reduce operational risks from expired certificates, service outages, and rapidly changing cryptographic requirements. Centralising certificate and DNS management has become more important as businesses face tighter compliance demands and a growing number of digital identities.

Platform changes

During the year, DigiCert added new integrations for its Trust Lifecycle Manager product with F5, HashiCorp, Jamf, and NetScaler. It also made DigiCert ONE available through AWS Marketplace and released its TrustCore software development kit as open source.

DigiCert filed 29 patents and received 12 grants, bringing its total patent portfolio to 230. Half of the new filings focused on artificial intelligence and post-quantum cryptography, two areas drawing increasing attention from security vendors and enterprise buyers.

Another notable development was the acquisition of Valimail, an email authentication company. The deal extends DigiCert into email security, including tools designed to reduce phishing, spoofing, and domain impersonation.

According to DigiCert, Valimail surpassed 100,000 customers during the year. It also launched a BIMI Simulator, a tool intended to help brands assess how their email presence appears to recipients.

Industry demand

DigiCert pointed to market recognition as another factor in its momentum, including being named a leader in the IDC MarketScape for worldwide certificate lifecycle management.

It also cited a commissioned Forrester Total Economic Impact report on DigiCert ONE. According to the study, customers using the platform achieved a 312% return on investment over three years, with payback in less than six months and more than USD $2.8 million in revenue and cost efficiencies tied to certificate automation and centralised management.

That focus on economic returns comes as security spending faces greater scrutiny from finance teams. Vendors increasingly frame certificate lifecycle management not only as a cybersecurity necessity, but also as an operational issue that can affect uptime, audit readiness, and staffing costs.

Partnerships

DigiCert said it was selected by ASC X9 to provide managed PKI infrastructure for the financial services industry. The designation gives the company a role in a sector where secure identity infrastructure and certificate controls are closely tied to regulatory standards.

It also highlighted work with Panasonic on secure Matter adoption in the Internet of Things market. In a separate collaboration, DigiCert took part in a US National Institute of Standards and Technology initiative focused on software supply chain and DevSecOps security.

Those partnerships suggest DigiCert is trying to extend its reach beyond traditional certificate issuance into connected devices, software development, and cloud infrastructure. The strategy mirrors a wider market trend in which trust services are being folded into broader security and operational platforms.

Global footprint

DigiCert expanded its infrastructure with new regional instances of DigiCert ONE, including a locally hosted deployment in India. It now operates more than 30 service instances across Australia, Europe, India, Japan, and North America.

Regional deployments have become more important for security providers as customers seek local hosting to meet data residency, sovereignty, and audit requirements. For multinational companies, the challenge is often to apply consistent security controls across regions while also meeting local rules on where data and cryptographic services can be handled.

"FY26 was a breakthrough year for DigiCert," said Dr. Amit Sinha, CEO of DigiCert. "We expanded our DigiCert ONE platform, deepened our partnerships, and delivered record Q4 ARR performance. Organisations are prioritising digital trust as foundational security infrastructure, and DigiCert is leading that transformation."
