- Credentials should be encrypted at rest with AES-256, scoped per-tenant, and owned entirely by the platform. If a vendor can't explain exactly where a token lives at every stage of its lifecycle, that's a strong signal the platform wasn't built for the enterprise customer.
- Each integration execution needs to run in a sandboxed environment per customer. One customer's high-volume sync shouldn't degrade another customer's performance, and isolation is an architectural requirement that no amount of documentation can substitute for.
- HMAC signature validation should reject unsigned webhook traffic before any payload parsing begins. A platform that accepts unsigned traffic or parses bodies before signature checks are complete is cutting corners.
- SOC 2 Type 2 is the baseline, not the finish line, and it's Type 2 for a reason. Type 2 attests controls sustained over time rather than verified at a single point in time, and requirements like HIPAA, GDPR, or CJIS depend on which markets a prospect operates in.
A B2B SaaS product team runs a two-week trial for an embedded iPaaS. The senior engineer hooks up a sandbox instance, passes a few JSON payloads back and forth between the product and Salesforce, and demos it to the team. Everyone is impressed, and the contract is quickly signed.
Then the platform hits its first enterprise security review.
The prospect's CISO drops a 225-question security questionnaire on the team. Suddenly, the team discovers the platform doesn't support fine-grained RBAC, can't isolate customer credentials at the tenant level, and is writing PHI into plain-text execution logs.
The deal is in jeopardy. Engineering is pulled off the core product roadmap to create some custom security add-ons to make the platform passable.
None of this showed up in the POC because the team was testing for connectivity and data transmission, not compliance.
When you sell integrations to enterprise customers, you are also modifying your customers' risk profiles. Below are the strategies and considerations that matter most when evaluating integration platform security.
Security is infrastructure
Most vendors pass the basic security spreadsheet. SOC 2? Check. SSO? Check. RBAC? Check. Encryption? Check.
Today, everyone has security controls of some sort, but how are those controls implemented under real-world conditions?
Let's consider two integration platforms. One encrypts everything, then logs OAuth tokens in plain text during debugging. The other provides per-tenant key scoping and automatic token refresh, and then scrubs the logs to ensure sensitive data doesn't appear where a support engineer could see it. Both platforms technically satisfy the encryption requirement, but only the second one survives an enterprise security review.
The SOC 2 badge tells you an auditor reviewed a software company's security program. That's a good starting point. Serious reviewers ask for the full report and read the exceptions and the customer-side controls it assumes. The badge doesn't tell you how credentials are stored, how execution environments are isolated, or what ends up in your logs when a healthcare integration processes a patient record.
The badge is a helpful starting point, but here's how teams differentiate between platforms that pass a checklist and platforms built to withstand real-world scrutiny.
What enterprise security requires
01 Look for credential-handling that goes beyond encryption at rest
Integrations live and die by how safely they handle API keys, OAuth tokens, and client secrets. A proper security approach abstracts this away from your integration code entirely. Credentials should be encrypted at rest with AES-256, decrypted only at runtime, and accessible only to the owning tenant, so one customer's secrets can never be accessed by another. The platform, not your integration (or your application), should own the OAuth token lifecycle end-to-end. The real-world failure scenario isn't a sophisticated attack. It's an engineer flipping on verbose logging to debug an issue and inadvertently persisting tokens somewhere a support engineer, or an attacker, could later read them. If a vendor can't explain exactly where a token lives at every stage of its lifecycle, that's a strong indicator the platform wasn't built with enterprise credential hygiene in mind.
02 Identify whether execution is properly isolated
Traditional iPaaS tools were built for a single company to connect its internal systems. As such, it can assume a single, trusted tenant. That assumption breaks down completely in the embedded iPaaS space, where integrations run on behalf of thousands of customers. Each integration execution needs to run in a distinct, sandboxed environment. One customer's high-volume sync cannot degrade another customer's performance, and their data streams can never cross paths. Ask the vendor where the isolation boundary sits: separate execution environments, network segmentation, or only application code. Then ask what stops one tenant's runaway job from affecting another. Isolation is an architectural requirement, not a policy one. No amount of documentation can substitute for it.
03 Validate webhook payloads before they reach your systems
Every public webhook endpoint is a potential entry point for malicious or malformed payloads. Webhook signatures should be validated before any payload is parsed. If the signature doesn't match the trusted provider, the payload is dropped at the gate, no exceptions. Authenticated payloads still need schema validation and safe input handling before they reach your internal APIs. A valid signature proves who sent a payload, not that its content is safe. Indicators that a platform is cutting corners here include accepting unsigned webhook traffic or parsing payload bodies before signature checks are complete.
04 Determine how much visibility and control the platform gives you during an incident
When an incident occurs, "unknown error" is not an acceptable answer. Security teams require complete visibility into the data lifecycle: what moved, when, who authorized it, and what changed – and all in real time, not after the fact. That means granular RBAC enforcing least privilege across every user role, audit logs covering every deployment and configuration change, and the ability to stream integration logs directly into your enterprise observability tools as events happen. Execution logs tell you what an integration did: whether it ran, which steps executed, what failed, and which customer instance was involved. Audit logs tell you what a person did: who changed a configuration, who deployed a new version, when, and under what authorization. A platform that can only reconstruct an incident after the fact, rather than show it as it happens, forces you to react instead of getting out in front of things.
05 Confirm the platform meets the compliance requirements your market expects
A SOC 2 Type 2 attestation is the baseline, not the finish line. And it's Type 2, not Type 1, because Type 2 measures controls sustained over time rather than verified at a single point in time (a critical difference). Beyond that, the requirements you need depend entirely on your customers: HIPAA (plus a signed Business Associate Agreement) for healthcare and PHI, GDPR for EU personal data, and the CJIS Security Policy for criminal justice information. If the platform lacks the attestations and agreements you need, that is the end of the conversation. There are no workarounds, and no amount of custom engineering closes that gap soon enough to matter.
How Prismatic addresses these requirements
Prismatic was built from the ground up for B2B SaaS teams that must provide integrations as product features. The security architecture reflects that. It wasn't retrofitted to satisfy enterprise buyers after the fact.
Prismatic infrastructure runs on AWS within a virtual private cloud, with core compute resources and databases in private subnets inaccessible from the public internet. Prismatic handles all patching, upgrades, and backups. Data is encrypted in transit with TLS 1.2+ and at rest across every storage system.
Prismatic encrypts all stored credentials with AES-256 and encrypts OAuth tokens with organization-specific keys. The platform never writes them to logs; they appear in a log entry only if your own custom code logs them, which is why log hygiene in custom code is part of your side of the shared-responsibility model. Each integration execution runs in a distinct, isolated environment. One customer's integration instance cannot reach another's execution environment or data.
Prismatic maintains a SOC 2 Type 2 report, signs Business Associate Agreements for HIPAA-covered customers, offers a GDPR Data Processing Addendum, and supports CJIS-compliant deployments on our AWS GovCloud stack. That combination covers healthcare, the EU market, and criminal justice information.
Security features have value beyond defense
Some teams treat integration security as purely defensive functionality. For them, it's a cost of doing business or a box to check to close the deal. While that framing is understandable, it's also shortsighted, since it badly undervalues what a proper security posture can bring to enterprise deals.
When your integration platform holds the necessary attestations and compliance commitments, you walk into enterprise security reviews with documentation that would otherwise have to be produced from scratch. A six-week security review gets a whole lot shorter when the answers are already documented, independently audited where it matters, and available on request through a trust center. A signed Business Associate Agreement and HIPAA-aligned controls unlock healthcare deals. CJIS unlocks public safety. Without them, those markets are simply off the table, no matter how strong the rest of the platform is.
Every piece of security infrastructure your engineering team codes is eating time they're not spending on your core product. A platform that handles credential management, compliance documentation, and multi-tenant isolation allows your engineers to keep coding while the security review is underway.
The question every embedded iPaaS vendor needs to answer
Don't ask, "Do you support enterprise security?" Everyone will say yes.
Instead, ask, "What happens when one of my customers sends a 225-question security questionnaire?"
That answer will tell you more than any feature matrix. The vendors that treat security as core architecture, not an afterthought, are the ones for whom that question has a short, confident answer. The others will hand the questionnaire back to your team to figure out.
