Security & data protection

Institutional data deserves institutional controls

Student records, payroll and sacrament registers are among the most sensitive data an organisation holds. Every system we ship is built with least-privilege access, encrypted transport, tested backups and an audit trail that answers "who changed this, and when?" — not as an add-on, but as the default configuration on day one.

HTTPS / TLS everywhere Role-based access Append-only audit log Tested restores 2FA & passkeys
Encryption in transit, secrets at rest TLS on every endpoint with HSTS, modern cipher suites, and credentials hashed with a memory-hard algorithm. Configuration secrets live outside the web root.
Least privilege by default Granular roles for registrars, bursars, HR, heads of department and IT. Nobody sees a module they do not need, and access is revoked the moment a role ends.
Append-only audit trail Every create, update, approval and deletion is recorded with the actor, timestamp and source address. Audit records cannot be edited from the application.
Backups that are actually restored Automated daily backups with off-site copies and a documented retention window — and periodic restore drills, because an untested backup is not a backup.
Hardened application layer CSRF tokens, strict Content-Security-Policy, parameterised queries, output escaping, rate limiting and session hardening — the same controls this website runs on.
Your data stays yours Institutional data is never sold, mined or shared. You can export it in open formats at any time, and on-premise deployment is available where policy requires it.
Deployment

Three ways to run it

Same software, different operating model. Pick the one that matches your IT capacity and your data policy — you can move between them later.

Most popular

Managed cloud

We host, patch, monitor and back up. You get a subdomain (or your own domain), a maintenance agreement and a named support contact.

  • Uptime monitoring and automated backups
  • Security patching handled by us
  • Fastest path to go-live

Policy-driven

On-premise

Deployed onto your own servers or campus data centre, where regulation or council policy requires the data to stay inside the institution.

  • Runs entirely on your infrastructure
  • Handover, runbooks and admin training
  • Optional remote support retainer
Discuss requirements
Phased

Hybrid

Public-facing components in the cloud, sensitive records on-premise — connected over authenticated APIs with clear boundaries.

  • Public website and admissions in the cloud
  • Student and payroll records held internally
  • Documented integration contracts

Delivery

How we deliver

A controlled implementation process that reduces project risk and keeps institutional stakeholders involved from the first workshop to the first term on the new system.

01

Discovery

We map workflows, users, approvals, reports, integrations and compliance requirements — on site where possible.

Output: requirements & scope document
02

Solution Design

We define modules, architecture, role permissions, milestones, data model and the deployment strategy.

Output: solution design & project plan
03

Build & Validate

We develop iteratively, review with stakeholders each cycle, and migrate approved institutional data with reconciliation.

Output: tested system & migration report
04

Deploy & Support

We launch, train each user role, document the system, monitor it and provide ongoing maintenance and improvements.

Output: live system, training & SLA
Under the hood

Boring technology, deliberately

We choose tools your next IT officer can maintain — widely supported, well documented, and cheap to host in Tanzania. No lock-in to a stack nobody local can hire for.

Questions

Frequently asked

The things institutions ask us before a deployment. If yours is not here, ask us directly — we answer honestly, including when the answer is "not yet".

Can the systems be customised for our institution?

Yes. Every deployment starts with a discovery phase where we map your workflows, approvals, reports and integrations, then configure or build the modules you need. Nothing is forced into a template that does not match how your institution actually works.

Do you migrate our existing data?

Yes. We migrate approved institutional data from spreadsheets or existing systems during the build and validation phase, with reconciliation reports signed off before go-live so you can prove the numbers match.

Where are the systems hosted, and who owns the data?

We deploy to secure cloud hosting with HTTPS, automated backups, role-based access control and audit logging. On-premise deployment is available where institutional policy requires it. Your institutional data belongs to your institution — we hold it only to operate the service, and you can export it at any time.

How do the systems work together?

They share one identity and one student record. An applicant admitted in OAS becomes a student in SIMS, is invoiced in the Billing System, and appears on the public website's admissions pages — without anyone retyping a name. You can also start with a single module and add the others later.

Can we start with just one module?

Yes. Most institutions start with the module that hurts most — usually admissions or billing — and expand once the first go-live is stable. Each system runs independently and integrates when you are ready.

What about payments and control numbers?

The Billing System issues control numbers and reconciles receipts against bank and mobile-money settlement files. Application fees in OAS and contributions in ChMS use the same payment path, so finance sees one consistent record.

How long does a deployment take?

A single module on our standard configuration typically goes live in 4–8 weeks including data migration and training. A multi-module rollout with heavy customisation is usually scoped in phases across one academic cycle.

How are user accounts protected?

Role-based permissions, enforced password policies, session timeouts, two-factor and passkey sign-in where supported, and an append-only audit trail of who changed what and when. Administrators can revoke access instantly.

What support do you provide after launch?

User training, written and video documentation, uptime monitoring, automated backups and a maintenance agreement covering fixes, statutory updates and continuous improvements.

Do the systems work in Swahili?

Yes. Interfaces, notifications and printed documents can be delivered in Swahili, English or both, and users can switch language themselves.
