Features and specs

What each product offers, as listed by its team.

ProtonMail 5 features
StackWeaver.cloud 8 features
  • End-to-End Encryption
    ProtonMail uses robust end-to-end encryption, ensuring that only the sender and the recipient can read the emails. This enhances the security and privacy of your communications.
  • Zero Access to User Data
    ProtonMail does not have access to user data or emails. This means that even ProtonMail cannot read your emails, providing an additional layer of privacy.
  • Swiss Privacy Laws
    Based in Switzerland, ProtonMail benefits from stringent Swiss privacy laws, which are some of the strongest in the world. This offers users greater legal protection against mass surveillance.
  • Open Source
    ProtonMail's encryption algorithms are open source, which means their code can be reviewed and audited by anyone, promoting transparency and trust.
  • User-Friendly Interface
    ProtonMail offers an intuitive and clean user interface, making it easy for users to manage their emails efficiently.

Possible disadvantages

  • Limited Free Storage
    The free version of ProtonMail offers only 500 MB of storage, which might be insufficient for users who need to store a large number of emails.
  • Paid Plans
    Advanced features and additional storage require a paid subscription, which may be a hassle for users looking for a completely free service.
  • Search Limitations
    Due to end-to-end encryption, the search functionality in ProtonMail is limited compared to other email services, as the search can only be performed on email subjects, not the content.
  • Compatibility Issues
    ProtonMail's encryption might not be fully compatible with other email services, potentially causing issues with sending and receiving encrypted messages.
  • Learning Curve
    New users who are unfamiliar with encryption concepts might find it slightly challenging to understand and use all of ProtonMail’s security features effectively.
  • Evidence Vault
    Upload compliance evidence once; every file gets a SHA-256 fingerprint and its own evidence ID
  • Evidence Review & Sign-off
    Partners accept or reject evidence with a reason, then sign it off; signed evidence is locked
  • Tamper-Evident Decision Record
    Every review and sign-off is chained per workspace, so any later change is detectable
  • Verifiable Evidence Packages

  • Partner Portal

Questions & Answers

As answered by people managing ProtonMail and StackWeaver.cloud.

How would you describe the primary audience of your product?

StackWeaver.cloud's answer:

Regulated fintechs, payment service providers and B2B SaaS companies in Nigeria and across Africa. In particular, CTOs, founders and compliance leads preparing for CBN examinations, NDPC audit returns, SOC 2 or ISO 27001 audits, bank security questionnaires or investor due diligence. The audit, compliance and advisory firms that serve those companies and want one place to run engagements with them.

Which are the primary technologies used for building your product?

StackWeaver.cloud's answer:

eact, TypeScript and Vite for the portal. Astro for the website. Cloudflare Pages and Workers for hosting and server functions. Supabase (PostgreSQL with row-level security, Vault and Storage) for data and evidence files. Clerk for sign-in. Paystack for payouts. SHA-256 hashing and an open JSON-based evidence package format.

What makes your product unique?

StackWeaver.cloud's answer:

StackWeaver is built for African regulation first. CBN AML/CFT (including the Baseline Standards for Automated AML Solutions) and NDPA sit alongside SOC 2, ISO 27001 and PCI DSS, rather than being bolted on as an afterthought.

It also treats evidence as something that must be provable, not just stored. Every file gets a SHA-256 fingerprint and an evidence ID. Every review and sign-off is written to a chained decision record that shows if anything was changed later. Evidence can be exported as a package in an open, documented format that an auditor can check without a StackWeaver account.

Finally, it pairs the platform with hands-on compliance engineering, so the evidence is actually produced, not just tracked.

Why should a person choose your product over its competitors?

StackWeaver.cloud's answer:

Most compliance automation tools are designed around US frameworks and US cloud stacks. If you are a Nigerian or African fintech, you need CBN AML/CFT and NDPA covered properly, local pricing, and a team that understands local regulators and banks.

StackWeaver gives you that, plus:

a portal your audit or advisory firm can work in with you, reviewing and signing off evidence in the same place; an evidence package your auditor, bank or investor can verify on their own; engineers who help implement the controls, not just a dashboard that lists what is missing.

What's the story behind your product?

StackWeaver.cloud's answer:

Our founder, Oluwafemi Ofobutu, kept seeing the same pattern in regulated fintechs. Engineering stopped being the problem, product stopped being the problem, and trust became the problem. Investors asked for evidence, enterprise customers asked about security, and regulators asked for proof. Most companies answered by producing more documents, more spreadsheets and more manual work before every audit.

StackWeaver was started to go the other way: make trust something a company demonstrates continuously through the way its systems operate. It began as compliance engineering for African fintechs and grew into a platform where evidence is collected once, reviewed, signed off and shared in a form others can verify.
