Identity security software from Cisco that supports multifactor authentication and secure access. Cisco Duo helps administrators verify sign-ins, review device trust, and apply access policies to supported applications and services.

Not to be confused with: Cisco Umbrella provides internet security; Duo verifies identity and access.

Cloud-delivered security from Cisco that uses DNS and related controls to help prevent access to malicious destinations. Cisco Umbrella gives IT teams centralized policies and security activity visibility. Additional web security functions depend on the licensed package.

Not to be confused with: Cisco Secure Endpoint protects endpoints through a separate product; Umbrella focuses on cloud-delivered internet security.

CK-12 is a free digital learning platform centered on FlexBooks and standards-aligned resources. It is designed primarily for primarily middle- and high-school learners, with content extending into elementary and college-preparatory subjects, with students, teachers, curriculum writers, and families using it to support open textbooks, simulations, practice, adaptive learning, and customizable stem resources.

Teachers can adopt, remix, and assign digital texts, interactives, questions, simulations, and practice while students use them for instruction, reference, or review. The product should be evaluated for the specific learners, instructional setting, and intensity of support a district intends—not simply as another source of digital activities.

Class Composer is an elementary class-placement tool that helps school teams create balanced classroom rosters for the next school year. Educators enter or import student characteristics, relationships, services, academic information, and placement considerations, then compare proposed class groupings.

The product supports the internal placement of already enrolled students; it does not collect family registration forms or establish SIS enrollment. It belongs under Student Scheduling / Class Placement and should be moved after the district relationships are retained.

ClassDojo is a classroom community and family-engagement platform used by teachers to share messages, photos, videos, announcements, events, and student learning updates with families. It also provides classroom tools for feedback, routines, portfolios, and schoolwide communication.

Its primary role is ongoing teacher-family connection rather than district-scale emergency notification. Families can use mobile or web access, communicate privately with teachers, receive translated messages, and follow classroom or school stories, while school leaders can coordinate accounts and schoolwide posts.

ClassLink is a K–12 access, rostering, identity-management, and application-analytics platform. LaunchPad gives students and staff a role-based single sign-on portal; Roster Server distributes SIS roster data to learning applications; OneSync automates account and group changes; and Analytics provides application-use reporting. Analytics+ is an additional offering with deeper analysis.

The products are designed to work as a shared connection layer across a district's technology environment. ClassLink can import SIS and directory data, transform it to the OneRoster standard, send only approved fields to vendors, support SAML, OAuth, and LTI access, and connect cloud storage and other school resources. This lets districts add or change applications without rebuilding a separate login and roster process each time.

LaunchPad is the user-facing application portal. District administrators use the ClassLink Management Console to administer their ClassLink environment. These are related parts of ClassLink, rather than evidence that a district has adopted an unrelated standalone system.

Application usage analytics for resources accessed through ClassLink LaunchPad. ClassLink Analytics organizes engagement information by application and school to support technology spending, implementation review, and professional learning decisions.

Not to be confused with: Analytics+ extends visibility to digital resources used outside LaunchPad; this record identifies Analytics.

Rostering software that connects student information system data to educational applications through OneRoster. ClassLink Roster Server manages scheduled data sharing, preprocessing, and vendor connections so schools can maintain consistent accounts and class rosters across learning tools.

Not to be confused with: ClassLink LaunchPad provides single sign-on; Roster Server provides roster data exchange.

classroom.cloud is a three-part K–12 platform for classroom management, student safeguarding, and basic IT device management. Teachers use it to view student screens, share content, control applications and web access, communicate, and keep students focused; safeguarding teams monitor concerning activity and student-submitted concerns; technology staff manage supported classroom devices and settings.

Because those functions serve teaching, student safety, and IT operations as distinct district responsibilities, classroom.cloud meets the original Integrated Systems concept more directly than most listings in this category. It should also be cross-listed with Classroom Management, Student Safety/Monitoring, and Device Management.

Closegap is a school-focused student wellbeing platform built around short, developmentally appropriate check-ins. Students can share how they are doing, ask to connect with an adult, and use brief self-guided social-emotional resources, while authorized staff receive timely signals about students who may need support.

The product helps schools identify concerns earlier, prioritize follow-up, and understand wellbeing patterns without relying only on referrals or periodic surveys. It supports early and crisis-intervention workflows, but it is not a clinical health record and should not be presented as a substitute for professional mental-health assessment or emergency procedures.

CodeCombat is a game-based programming curriculum and practice environment. It is designed primarily for upper-elementary through high-school learners beginning or extending computer programming, with computer-science teachers, students, after-school programs, and curriculum leaders using it to support coding syntax, computational thinking, problem solving, and computer-science concepts.

Students write real code to solve progressively structured game challenges while educators assign courses and monitor concept mastery. The product should be evaluated for the specific learners, instructional setting, and intensity of support a district intends—not simply as another source of digital activities.

CodeHS Pro is the paid school edition of CodeHS’s secondary computer-science curriculum and platform. It is intended primarily for middle- and high-school learners in computer science, cybersecurity, web, and technology courses, with students, computer-science teachers, CTE staff, counselors, and curriculum leaders using it to support programming, computational thinking, cybersecurity, web development, and course assessment.

Teachers deliver sequenced courses, coding exercises, projects, quizzes, sandboxes, and feedback while monitoring progress and code submissions. Districts should evaluate how the product fits adopted curriculum, student needs, instructional time, and the work educators must do around it.
