Building trust at the core: Nylas’ security & compliance program for communication APIs
• 5 min read
At Nylas, trust isn’t something we talk about lightly.
Our platform sits in the middle of some of the most sensitive workflows our customers run — email API, calendar API, and communications data that often contains personal, financial, and operational information. That’s not abstract risk. It’s real data moving through production systems, with real consequences if something goes wrong.
We operate with that in mind every day.
Lately, the industry has been having more open conversations about how security failures actually happen. Not as isolated incidents, but as breakdowns across systems, vendors, and assumptions. Those conversations are a good reminder of something we at Nylas have believed for a long time: security is only as strong as the weakest link in the chain.
At Nylas, security isn’t something we “achieve” and move on from. It shapes how we design systems, how we ship code, and how we make tradeoffs.
There’s a constant awareness that we are operating infrastructure that other companies depend on. That changes how you think. It means questioning defaults, limiting access wherever possible, and assuming that anything exposed unnecessarily will eventually be tested.
That mindset shows up early—in architecture decisions—and continues all the way through to how we monitor and respond in production.
The data that flows through Nylas is inherently sensitive. Emails and calendar data aren’t just records—they’re often the source of truth for how businesses operate.
Because of that, we take a layered approach to protection.
Encryption is standard, both in transit and at rest, using modern cryptographic protocols. Access is tightly controlled through least-privilege principles and scoped to what’s actually needed. Systems are instrumented so that unusual behavior doesn’t go unnoticed.
None of this is about checking boxes. It’s about recognizing the nature of the data and treating it accordingly.
There’s no single control that makes a system secure.
What matters is how everything fits together—how infrastructure, application logic, and operational practices reinforce each other. At Nylas, that means combining secure cloud infrastructure, continuous vulnerability management, proactive security posture management, secured SDLC practices, and development processes designed to catch issues before deployment.
We also rely on independent validation. External testing and audits help ensure we’re not just confident in our controls, but correct.
We maintain a compliance program aligned with widely recognized frameworks like ISO 27001, ISO 27701, SOC 2 Type II, HIPAA and global privacy requirements including GDPR.
But compliance, on its own, doesn’t equal security.
What it does provide is structure. It forces consistency, creates accountability, and gives customers visibility into how controls are implemented and maintained. From there, the real work is continuing to improve beyond the minimum requirements.
One of the clearest shifts in recent years is how often incidents trace back to third-party dependencies.
Companies don’t operate in isolation anymore. Every additional service, API, or integration expands the surface area of risk. And when something breaks, it rarely stays contained.
That’s why vendor selection has become a security decision, not just a product decision.
When evaluating partners, it’s no longer enough to ask what they do. You have to understand how they operate. How they think about access. How they respond to issues. Whether security is embedded in their culture or layered on after the fact.
We’re very aware that Nylas becomes part of our customers’ security posture.
That responsibility cuts both ways. It means holding ourselves to a high standard, but also being deliberate about the vendors and infrastructure we rely on internally. Risk doesn’t stop at our boundary—it extends through everything we depend on.
So we approach security as a shared system, not an isolated function.
There isn’t a point where security is “done.”
Threats change. Systems evolve. Assumptions that were safe a year ago may not hold up today. That’s why we treat security as an ongoing process—something that requires continuous investment, regular reevaluation, and a willingness to adapt.
Security and compliance at Nylas aren’t separate from the product—they’re part of how the product works.
We know the kind of data that moves through our platform. We understand the expectations that come with that. And we take seriously the role we play in our customers’ broader security posture.
As the industry continues to reckon with vendor risk and interconnected systems, one thing is becoming increasingly clear:
Who you choose to build with matters — especially when your application depends on secure, reliable infrastructure for email, calendar, and communications data.
Platforms that enable communication workflows, such as email APIs, link tracking, and email tracking, are…
Building security by design is crucial, especially for startups and small businesses, where resources are…
In a time where cyber threats are increasingly sophisticated and frequent, fostering a security-first culture…
