What WeOnlyDo Software does

WeOnlyDo Software, legally Secure Plus d.o.o., is a Croatian software developer founded in 1998 and headquartered in Osijek, Croatia. The company designs, develops, and maintains a portfolio of more than 20 royalty-free COM, ActiveX, and .NET components aimed at Windows software developers who need to embed secure networking, file transfer, and email functionality into their applications. The catalog spans two main pillars — security components (wodCrypt, wodSSH, wodSSH.NET, wodSFTP, wodSFTP.NET, wodFtpDLX, wodSSHTunnel, wodSSHServer, wodFTPServer, wodVPN) and mail components (wodSmtp, wodPop3, wodImapServer, wodSmtpServer, wodPop3Server, wodMailbox, wodMailServer) — plus general protocol components (wodHttpDLX, wodWebServer, wodXMPP, wodAppUpdate). All components are written in managed C# or VC++, integrate OpenSSL3 for cryptography, and are certified for Windows 11 and Visual Studio 2022; recent updates in 2024-2025 have added TLS 1.3, post-quantum key exchange (mlkem768x25519-sha256), and WebSockets support.

The company sells primarily through a direct-to-consumer self-serve channel: customers purchase one-time perpetual licenses per developer on the company website, with immediate digital delivery via the Avangate payment processor, and 1 year of support and updates included. Optional source-code licenses are available at a premium but do not grant modification rights. A reseller network handles enterprise customers who need to transact via purchase order. Revenue is therefore driven by per-developer license fees ranging from $99 (wodAppUpdate, wodSmtp, wodPop3) to $409 (wodMailServer bundle), with individual developer and ISV customers as the primary segment, and enterprise/IT use cases (e.g., email backends, SSH/SFTP connectivity across distributed sites) as a secondary segment. The company is privately held, has 1-10 employees, has raised no external funding, and shows no M&A or leadership change activity; president Kresimir Petric has led the business since inception. Customer logos referenced in public testimonials include Cisco, Nokia, Siemens, Verint, IDM Computer Solutions, Leaf Wireless, and Dionach, suggesting a long-tail distribution rather than concentrated enterprise dependencies.

Direct peers

• Bitvise: Provides SSH/SFTP server and client software for Windows (WinSSHD, Tunnelier, FlowSsh). Overlaps directly with WeOnlyDo's SSH/SFTP server and tunneling components and competes for the same Windows security-developer customer.
• Chilkat Software: Provides commercial software components and libraries (SSH/SFTP, FTP, mail, encryption) for .NET, ActiveX, C++, Python, and more. Closely comparable business model: per-developer perpetual licenses, royalty-free runtime, and similar protocol coverage to WeOnlyDo.
• /n software: Sells developer component suites (IPWorks, IPWorks SSH/SFTP, IPWorks Mail) targeting .NET, COM, ActiveX, Java, and other stacks. Directly competes with WeOnlyDo on the same Windows developer component category with overlapping SSH, SFTP, FTP, and mail protocols.
• Rebex: Sells .NET components for SSH, SFTP, FTP, mail (SMTP/POP3/IMAP), and cryptography. Targets the same Windows/.NET developer buyer as WeOnlyDo with a similar licensing model and overlapping protocol suite.
• Catalyst DevWorks (formerly Dart): Sells PowerTCP and PowerSNMP component suites covering FTP, SFTP, SSH, mail, and HTTP for .NET and ActiveX. Direct overlap with WeOnlyDo's product scope and target buyer.
• MarshallSoft: Long-running vendor of Windows developer libraries (serial comms, SSH, encryption, mail). Targets the same Windows/C/C++/.NET developer customer with similar perpetual-license commercial SDKs.
• EnterpriseDT: Develops .NET and Java components for FTP/SSH/SFTP and other protocols. Sells to the same Windows/.NET developer segment with a comparable commercial licensing model.
• ComponentAce: Sells developer components for .NET, ActiveX, and VCL including mail, FTP, and security protocols. Comparable component-vendor model to WeOnlyDo serving Windows developers.

Broad incumbents

• SSH Communications Security (Tectia): Original commercial SSH vendor offering enterprise-grade SSH/SFTP products and broader secure communications portfolio. Competes with WeOnlyDo on SSH/Telnet but at a much larger, enterprise-solutions scale rather than per-developer SDKs.
• Microsoft: Provides native SSH/SFTP, mail, and HTTP protocol support across .NET libraries, Azure, and Windows platforms. As the platform owner, Microsoft is a broad incumbent whose built-in capabilities compete with WeOnlyDo's value proposition for Windows developers.
