Gibbon versus PowerSchool
Compare	Gibbon	PowerSchool
Verdict	Depends	Depends
Best for	Schools with in-house IT	Large K-12 districts
Who it's not for	Schools without a sysadmin . the CVE history demands fast patching	Small schools . far too heavy and costly
Privacy	Rough record: multiple RCE, SQL injection, and file-inclusion CVEs between 2023 and 2026; patching discipline is mandatory.^⁹	Major Dec 2024 breach exposed student/teacher data; active XSS CVE; basic security step reportedly missed.
Support quality	Guess: community forum support, no vendor SLA	2.1/5 Trustpilot; complaint threads abound
Public sentiment	No substantive user reviews of the school platform surfaced; most 'Gibbon' search results concern unrelated products like slacklines and speakers.^⁵	Reviews split sharply: G2 reviewers praise ease of use while Trustpilot raters and many teachers on Reddit report frustration.¹⁶
Biggest gotcha	Self-hosted: you provision hosting, run upgrades, and must patch fast when RCEs land^¹	Dec 2024 breach triggered class-action lawsuits; expect security scrutiny in procurement
