About

HailBytes SAT is a self-hosted phishing simulation and Security Awareness Training platform for IT and security teams that want continuous user testing without per-seat licensing or sending employee data to a third-party SaaS. Continuous testing with targeted micro-training measurably reduces successful phishing attacks over time. Key capabilities include unlimited campaigns, AI-assisted phishing templates, post-click training modules and quizzes, credential-capture landing pages, and user segmentation by department, risk tier, or cohort. Enterprise features include RBAC, MFA/TOTP, SSO/OIDC, SAML, SIEM export, and any SMTP provider supported. Deploys from AWS or Azure Marketplace in under 30 minutes on a hardened image you control. Pricing starts at $0.24/vCPU/hour (roughly $4,200/year), typically 70 to 80% less than commercial alternatives. Includes a 30-day free trial. Your account, your data, no vendor lock-in.

About

SubsiMail is a self-hosted cold email sequencing platform. Prospect lists, templates, connected inboxes, and all campaign data live in your own database, not a third-party SaaS. It's built as a self-hosted alternative to Instantly, Smartlead, lemlist, and Apollo, with flat per-inbox pricing instead of per-seat fees, full data ownership and export, no content review, and no third-party access to your contacts or campaigns. Runs as a single Docker container on any $5 VPS. Connect Gmail, Outlook, or any SMTP/IMAP inbox; build multi-step sequences with merge fields and reply detection; manage per-user roles (admin/manager/view-only) with a full audit trail; and integrate via a REST API with personal API keys. The first connected mailbox is free forever.
