Education software development services

We begin with compliance-by-design: at the project initiation stage, we create a register of applicable norms and standards for interoperability, content, accessibility, and privacy. These requirements are traced in a requirements traceability matrix and included in acceptance criteria and CI/CD gates. We simultaneously conduct DPIA/PIA and threat modeling to identify data processing risks and architectural mitigations in advance.
We ensure interoperability and correctness of training scenarios through a combination of architectural solutions and formal verification. Content packages and telemetry are validated against SCORM/xAPI; We connect external educational tools via LTI 1.3 with signature and privileged assertion exchange; assignment banks and results are via QTI; and user, enrollment, and grade synchronization is via OneRoster. We build single sign-on using SAML 2.0/OpenID Connect. We use ADL/1EdTech test suites and automated integration tests; without the successful execution of critical scenarios, the build fails in production.
We implement accessibility as a shift-left practice. Interface and content design is compliant with WCAG 2.1 AA (contrast, focus indicators, keyboard navigation, media alternatives, correct live regions, and form validation). Automatic checks are supplemented by manual audits with NVDA/JAWS/VoiceOver and “keyboard only” scenarios. We support i18n/L10n (including RTL), standardize date/number formats and terminology to ensure compliance doesn’t conflict with usability.
We implement privacy and legal requirements using privacy-by-design principles. Our architecture follows the GDPR: minimizing and limiting processing purposes, lawful grounds, access control, retention periods, and deletion. We implement DSR (access/rectification/deletion) procedures, transaction logs, and managed logging. We ensure data residency (EU/US, etc.), apply SCCs for cross-border transfers, conclude DPAs, and maintain a register of subprocessors. If a project falls within the FERPA/COPPA/CCPA framework, we add specific policies and consent mechanisms.
We ensure security through a secure SDLC and operational controls. We adhere to ISO 27001 and OWASP ASVS/SAMM standards: traffic encryption (TLS 1.2+) and data on storage media (AES-256), key management via KMS/HSM, RBAC/ABAC models, WAF, network segmentation, centralized logs and audit trails, backups, and BCP/DR plans with RPO/RTO targets. Our pipeline includes SAST/DAST/SCA, SBOM, regular dependency updates, external pen tests, and proven IR playbooks with SLAs.
We document quality and validation. We have separate test plans and regression suites for SCORM/xAPI/LTI/QTI and SSO; we conduct UAT with methodologists and instructors using real-world use cases. The Client receives a compliance package: a compliance matrix, test and pen test reports, an accessibility report, a DPIA, a handler registry, and release artifacts. After launch, we support continuous compliance: monitoring, WCAG retests, periodic audits, 1EdTech/W3C/regulatory update reviews, and managed integration changes.
This process makes SumatoSoft solutions predictable for procurement and audits, reduces legal and operational risks, and ensures that the platform actually meets educational standards, not just claims to.

Yes. As part of our education software development services, we design and develop both native mobile solutions and cross-platform learning products, providing a unified experience across phones, tablets, and browsers. SumatoSoft handles the full cycle, from strategy and design to app publishing and support, delivering custom edtech solutions that are scalable and secure.
When the priorities are mobile device capabilities and a high level of interactivity, we offer native apps for iOS and Android. When speed to market and optimal total cost of ownership are important, we use a cross-platform stack (e.g., React Native or Flutter) with a common codebase for mobile platforms. For easy entry and rapid distribution scenarios, we use responsive web Clients and progressive web apps that run directly from the browser.
For enterprise scenarios, private distribution is available through Apple Business Manager and Managed Google Play.
We test on a wide range of devices: functional, load, and network checks, including resilience to unstable connections and limited battery life. We measure response times and resource consumption to ensure a comfortable learning experience even on mass-market devices. After release, we provide support with agreed-upon response times, regular updates, and further functionality development.
The result for the Client is a unified learning environment that is equally user-friendly across all devices, with measurable engagement and course completion, reduced time to market for new modules, and a predictable cost of ownership.

Student and institutional data security is built into the architecture and development process from day one and is supported by operational controls throughout the solution’s lifecycle.
We operate according to “security-by-design/by-default” principles: we maintain a security management system (in accordance with ISO 27001), maintain an asset and risk register, implement delineation of roles and responsibilities, and strictly manage access and change controls. For projects involving personal data, we conduct data protection impact assessments (DPIAs) and establish contractual guarantees in data processing agreements (DPAs).
We separate environments (dev/test/stage/prod), segment the network, implement the principle of least necessary access, and mandate multi-factor authentication. We integrate single sign-on with corporate identity providers; application-level permissions are defined through role/attribute models, and all administrative actions are logged.
We encrypt traffic and stored data. Keys are managed by the cloud provider with separate access policies. We enable version control and secure secret storage, and use anonymization/pseudonymization for analytics. We comply with GDPR requirements: data minimization, purpose limitation, retention periods, jurisdictional residency, and the exercise of data subject rights.
We apply secure coding standards and mandatory reviews, employ static and dynamic code analysis, dependency scanning, and container scanning. Critical components are covered with automated tests and CI/CD policies. We regularly conduct vulnerability scanning and external penetration tests, remediating findings according to agreed-upon SLAs.
We evaluate external suppliers and integrations, maintain a register of subprocessors, and update contractual and technical security measures. Software is delivered through trusted registries; we use lists of components (SBOM) and integrity control.
Upon request, we also provide a set of evidence: policies and procedures, test results, excerpts from pen test reports, a compliance matrix, availability artifacts, and DPA samples. This approach reduces legal and operational risks, facilitates audits, and ensures predictable solution operation.
