Onam Security API Security

Onam Security API Security is a cloud API posture product for security teams that need to inventory endpoints and spot configuration or exposure risks across cloud environments. It is best suited to organizations managing APIs across multiple providers; its read-only approach provides broad visibility without sending test traffic, but does not assess API behavior through active requests.

Overview

The product discovers API surfaces across gateways, load-balanced endpoints, function URLs, and ingress routes, then evaluates them against 241 application and API security rules. By comparing endpoints with a network graph, it can identify APIs reachable through open paths and flag shadow or orphaned APIs. That combination makes it useful for finding overlooked exposure as well as checking configuration.

Scanning reads configuration through read-only cloud APIs rather than sending traffic to the endpoints. This is a good fit for posture reviews that should avoid active testing, but teams still need other methods to assess how APIs behave under real requests.

Key features

• Multi-environment discovery: Coverage spans AWS, Azure, GCP, OCI, Alibaba, and Kubernetes. That breadth benefits teams with distributed cloud estates; a team focused on a narrow environment may not need as much coverage.
• Focused configuration checks: The 241 rules address authentication, authorisation, throttling, WAF association, TLS policy, and logging. This gives security teams a substantial set of posture controls to review without implying active validation of those controls.
• Exposure context: Cross-referencing APIs with network paths helps distinguish endpoints that are reachable through open routes and brings shadow or orphaned APIs into view. That is valuable for prioritizing visibility gaps, though it is not a substitute for request-based testing.
• Operational connections: The integration catalog includes Jira, ServiceNow, Slack, Microsoft Teams, PagerDuty, Splunk, Azure Sentinel, AWS Security Hub, GitHub Actions, and GitLab CI. Teams using these systems can connect API posture work to ticketing, notifications, security operations, or CI workflows.
• Platform assurances: Onam documents a unified REST API under /api/v1. Its Trust Center lists SOC 2 Type II, ISO 27001:2022, ISO 27017, and PCI DSS v4.0 as achieved, and states that data is encrypted at rest with AES-256 and traffic uses TLS 1.3. These may help organizations evaluating governance and platform security requirements.

Pricing

The Free plan costs nothing and is billed forever. It allows one cloud account and up to 500 resources, keeps findings for 30 days, and includes community support. That is a practical starting point for a limited deployment, but the account and resource caps constrain use across larger or multi-cloud environments.

Pro costs $22 a month, billed per resource / month and billed monthly. It removes the cloud-account limit, includes all 29 engines, extends finding history to one year, and provides email support with a stated response time under 24 hours. The per-resource billing means the monthly price grows with the footprint, so the entry price alone does not establish the cost of a large environment.

Enterprise uses an annual contract with custom pricing. It adds custom data retention, a contractual 99.9% uptime SLA, priority support under four hours, and a choice of SaaS or on-premises deployment. This tier is better suited to organizations that need contractual service commitments or deployment flexibility; the Free plan and Pro do not include those stated terms. A 14-day trial is available for evaluating the product before choosing a plan.

Platforms

Onam lists API, self-hosted, and web platforms, with a hybrid deployment model. Enterprise explicitly offers SaaS or on-premises deployment, making it the clearest fit for organizations that require that choice. The Free and Pro plan details do not state the same deployment options.

Who it's for

Onam is aimed at teams seeking visibility into exposed, unauthenticated, or unmonitored APIs across cloud environments. It is particularly relevant when security staff need to inventory endpoints, check configuration, and understand network exposure across several providers. Teams that need active API behavior testing should pair it with a testing approach that sends requests, rather than treating posture scanning as a complete assessment.

Pros and cons

• Pro: Discovery covers six cloud environments and Kubernetes, giving multi-cloud teams a broad view of API surfaces.
• Pro: Network-path analysis can surface reachable, shadow, and orphaned APIs alongside configuration findings.
• Pro: Read-only scanning avoids sending traffic to APIs, which suits configuration-focused reviews.
• Con: No active API traffic testing means the product does not show how endpoints respond to real requests.
• Con: Free is limited to one cloud account, 500 resources, and 30-day finding history, which can be restrictive beyond a small evaluation.
• Con: Pro is billed per resource per month, so costs scale with the monitored footprint.

Alternatives

For a comparison across API-focused products, see the API Security Software directory. Onam's emphasis is cloud discovery and configuration posture rather than active traffic testing.

• Zscaler Private Access is a paid private-access option with a Standard plan described as limited private access for 5% of users.
• Skyhigh Private Access is another paid private-access option.
• Bedrock Data Security Platform has a free Snowflake-only plan with weekly scans; choose it when that narrower data-security scope is the priority.
• Cyberhaven Data Security Platform is a paid alternative with pricing provided by request and a product demo offered by the company.
• Forcepoint Data Security Cloud is a paid option with pricing by request.
• Netwrix Password Secure is a paid alternative whose self-service plan starts at $60 a year, with a minimum one-year purchase commitment.
• Proofpoint Email DLP and Encryption is a paid alternative.

Verdict

Choose Onam Security API Security when your team needs a cross-cloud inventory of API endpoints, configuration checks, and visibility into network exposure without active testing traffic. Its breadth of discovery and read-only posture scanning are the core reasons to consider it. Look elsewhere or add a separate testing tool if you need to evaluate API behavior through requests, and weigh Pro's per-resource billing against the size of your environment.
