How EdTech companies store data plays an important role in their data security. But what are their options?


  • EdTech companies can store school data in one system. Or, they can have each school use a separate system.
  • Single-tenant systems provide each school with a separate system of servers. This decreases the chance of a database-wide security incident. However, more servers equals more security vulnerabilities.
  • Multi-tenant systems, which keep data in one place, are a more secure option. They allow EdTech companies to better focus their security resources and decrease exposure to bad actors.

Data Storage 101

Let's go over some terms:

School Data: Info about an EdTech company's school customers, including the names and emails of students and staff.

Server: A system that stores data and sends it from the EdTech company to schools, and vice versa.

Single-tenant system: A system of servers that only stores data from one school or district.

Multi-tenant system: A system of servers that stores data from multiple schools or districts.

What's the difference between a single-tenant system and a multi-tenant system?

School data can either be stored in a single-tenant system or a multi-tenant system.

  • A single-tenant system only interacts with ONE school or district's data.
  • A multi-tenant system can interact with multiple schools or districts.

Let's dive into the pros and cons of each.

The pros and cons of single-tenant systems:


  • If the database has a security breach, it's likely that not all of the data will be compromised. This is because the attacker would only have compromised one of the multiple systems.


  • More systems creates more security vulnerabilities. In other words, more places for bad actors to hack into.
  • More systems are more challenging to manage. For example, it's harder to make database-wide changes to multiple systems. It's also harder to make sure all systems are secure.
  • Single-tenant systems require more complex software to support. This is itself a source of security challenges, including fixing database-wide bugs and maintaining a more complex code deployment strategy.

The pros and cons of multi-tenant systems:


  • Using one system creates the least possible number of security vulnerabilites.
  • It's easier to make database-wide updates and prevent bugs.
  • It's easier to make one system secure. There's less to track, manage, update, and protect.


  • Using a single system potentially leaves more data exposed during a security incident.

Which is better for data security?

So, there are pros and cons to each kind of server. However, one takes the win when it comes to security.

Multi-tenant. Why? Because less exposure to security vulnerabilities is key to protecting school data. That's why we (Edlink) use a single multi-tenant system.

Additionally, using single-tenant systems stretches security resources too thin. It's difficult for companies to ensure every server is equally secure at all times.
