Deep Safe wanted to launch a B2B SaaS dedicated to third-party cyber risk management (TPRM). The starting point was simple: most companies now have to monitor the security of their suppliers and partners, yet still do it in manual spreadsheets, with no automated tracking and no solid oversight.

In practice, that often means a frozen annual audit, data that goes stale within weeks, and no way to react when a risk changes during the year. Third-party cybersecurity remains something handled for regulatory compliance, not as a real management tool.

The stake for Deep Safe? Moving companies away from this outdated annual-audit model and giving them a real tool that continuously manages the security of their ecosystem.

The real challenge was not building yet another dashboard. It was turning a raw cyber rating into a real decision-making tool, usable every day by teams who are buying a cybersecurity product precisely — and who will therefore accept no compromise on technical quality.

We had to integrate and harden data collection by ingesting SecurityScorecard feeds (nearly 190 incident types, 3-level scoring, threat intelligence) through a daily sync resilient to API outages, while guaranteeing a flawless level of security that meets the expectations of expert clients.

Another sensitive point: the platform had to be sellable from day one, with 4 distinct plans, strict usage quotas per tier and an autonomous billing engine. A complete multi-tenant SaaS build.

We designed and built the entire multi-tenant SaaS in 7 strategic stages, split into 2 tracks: business and product.

1.The business side: turning cyber data into a management tool
We built an outage-resilient SecurityScorecard connector to continuously ingest incident and scoring feeds without losing data when the API goes down. We then built third-party lifecycle management (onboarding, monitoring, offboarding), a detailed 5×4 risk matrix crossing likelihood and impact, supplier questionnaires to complement automated data with declarative data, and a module that flags required fixes and warns as soon as a supplier certification is about to expire.
2.The product foundation: a multi-tenant SaaS ready to sell
We set up secure authentication (MFA, 5-level RBAC, OAuth) that meets the expectations of a cybersecurity product, and server-side PDF/CSV export engines to generate client deliverables without relying on the browser. Plus Stripe billing coupled with automatic access management based on the subscribed plan, limiting data volume and requests accordingly.

Weekly sync meetings

Every week, a checkpoint let us validate progress, adjust priorities and prepare the next sprints.

Prototyping in Figma

Before coding, every journey (administrator, risk analyst, end client) was mocked up interactively. Deep Safe could test the interface, adjust the UX and validate choices very early on.

Continuous test environments

Throughout development, we gave the client pre-production (staging) environments. As soon as a component (connector, risk matrix, billing) was ready, the client could use it in real conditions and send us feedback so we could iterate quickly.

The client keeps full control at every step and sees their product take shape in real time: no black box, no bad surprises at delivery.

To build a complete multi-tenant SaaS with continuous ingestion of external data, real-time risk calculations and dynamic billing, we selected several technologies:

IntegrationsSecurityScorecard (outage-resilient connector), Stripe (billing + automatic access management)
AuthenticationMFA, 5-level RBAC, OAuth

~119 features delivered

4 distinct commercial plans with usage quotas per tier

~190 incident types ingested continuously via SecurityScorecard

We delivered a SaaS ready to sell, offered in 4 plans and operational from go-live. Beyond the technical deliverable, the platform lets Deep Safe's clients switch from an outdated annual-audit model to a real tool that continuously manages the security of their ecosystem.
