OpenSSL vs G2

OpenSSL and G2 both land on Depends.

OpenSSL

Depends

Confidence: Medium

Use it if you're a developer who needs TLS/crypto inside software . it's free, standard, and runs everywhere.

Depends

Confidence: Medium

Buyers shortlisting B2B software should use G2 free as one input, cross-checked against Capterra or TrustRadius.

OpenSSL versus G2
Compare	OpenSSL	G2
Verdict	Depends	Depends
Best for	Developers embedding TLS/crypto in software	B2B software buyers shortlisting tools
Who it's not for	Buyers shopping for a purchasable product . it's free software	Vendors without five-figure budgets
Privacy	Long CVE history from Heartbleed (2014) through a 2025 critical pre-auth RCE and 12 zero-days found in 2026; patching is your responsibility.^⁴	No public security page found; UpGuard reports no phishing; G2's own DPA references a past data breach.
Support quality	Community mailing lists; SLAs need vendor contracts	Trustpilot and BBB complaints about G2's service
Public sentiment	Sentiment splits: it's the trusted default running the internet's TLS, yet developers routinely slam its difficulty, code quality, and maintenance.^¹	Buyers find G2 useful for breadth, but sentiment on G2's own service skews negative on Trustpilot and Redditors weigh it against Capterra and Trustpilot.
Biggest gotcha	No patch service: you track, test, and deploy every OpenSSL update yourself	Vendor contracts are negotiated and opaque; budget five figures annually before committing.
