Acalvio ShadowPlex vs Heralding: Side-by-Side Comparison (2026)

Heralding

Security teams running small to mid-sized networks who want credential intelligence without deployment complexity should start with Heralding. It collects plaintext credentials across SSH, HTTP, SMTP, and a dozen other protocols through a lightweight honeypot, giving you immediate visibility into what attackers are actually trying; the 388 GitHub stars and zero licensing friction mean you can spin it up in minutes to see if credential harvesting is happening in your environment. Skip this if you need SIEM integration, alerting automation, or honeypot management at scale; Heralding is deliberately minimal, which is why it works.
