This document provides an outline of the security policies and standards we adhere to.
This document does not describe all details. Some information will only be shared with other parties on the basis of a non-disclosure agreement, and we reserve the right to not to share any information that could compromise the security of our platform or our customers’s websites.
Python is a language with strict security standards and policies. Python and modules in its standard libraries are subject to very close scrutiny. Vulnerabilities are rare and dealt with promptly.
Django inherits Python’s advantages and builds on them. Over the years it has earned a particularly strong reputation for very high security standards, thanks to the quality of its codebase and the policies it has adopted.
Django provides robust security out-of-the box. Core components and tools such as its authorisation framework, permissions framework and templating language have been tried, tested, hardened and improved, on a vast scale, over many years.
Django also configures security into its projects by default, and encourages good security by making it easier to do things the secure way.
Pre-public Django security patches¶
As a trusted, large-scale host of Django projects, we receive advance notification from the Django Project about security releases, which means that we are able to have security patches in place before vulnerabilities are made public.
A project’s web application containers and database are not directly accessible outside our network.
All traffic to our sites are directed through our Load Balancers, before reaching the application runners that orchestrate users’ containerised applications.
All levels are redundant, including PostgreSQL clusters and cloud media storage instances.
All connections are encrypted, even within our architecture.
Divio security monitoring¶
We monitor and log activity within and into our systems, and use automated systems to alert our infrastructure team to unusual traffic or behaviour.
Details of these systems are not disclosed to other parties.
Divio makes use of known services, such as the well-protected AWS and MS Azure stacks, that enjoy an international reputation for robustness.
Details of other providers can be supplied on application, under the terms of a non-disclosure agreement.
Security options for Divio users¶
We’re able to add further protection for our users for their projects. For example, we offer:
free SSL certificates to all customers and HTTPS by default
offer security patches and layers, proactively, in response to significant CVEs
CloudFlare DDoS protection
amongst other benefits.
Divio uses Docker-based containerisation for deployment, which contributes extra layers of security to our infrastructure.
Containerisation isolates running instances from each other. A vulnerability or even a breach affecting one site remains isolated to that particular instance.
Our containerised architecture makes it very easy to apply important software patches and updates. Fresh containers can be deployed to replace ones running outdated software without missing a beat, and we can apply updates - even major updates - to parts of the infrastructure without disrupting services. Similarly, updates can be applied to users’ projects without any disruption to service.
Finally, the portability of Docker containers means that users’ websites, already safely isolated from the machines and systems that host them, can be moved away very quickly should the hosting system suffer an attack or a breach. Users applications will never be tied down to a compromised infrastructure.
Backups are executed automatically as well as on-demand, stored separately and encrypted.
General code security and integrity¶
We adopt industry best-practices for security both in our own infrastructure and the projects we host for our users.
We use well-tested security libraries and do not create our own. We never bypass built-in protections offered by our technology stack, and make full use of them.
Staff security policy¶
Divio maintains a formal internal security policy, with which all staff are familiar. This covers such fundamental topics as multi-factor authorisation, reporting, recording, online accounts, handling of physical devices and so on.
Some details of our staff security policy can be supplied on application, under the terms of a non-disclosure agreement.
Incident response plan¶
Divio maintains a formal Incident response plan, governing incidents are recorded, escalated, dealt with and followed-up.
Security report handling¶
We have a dedicated security team, and encourage responsible reporting by providing dedicated and clearly advertised security contact details. We take all reports seriously and respond to them promptly.
We regularly run security tests against our own software and infrastructure. This includes penetration tests run by expert third-party security organisations.
Some details of our testing regime and its results can be supplied on application, under the terms of a non-disclosure agreement.
We are implementing the ISAE 3402 assurance standard, that allows us to demonstrate good security practices are in place and operating effectively. ISAE 3402 is a newer mechanism for assurance, with wider scope, that evaluates practices in a real-world context.
Our implementation of ISAE 3402 meets the requirements of clients with very strict demands in the banking sector that use the Divio platform.
We are in compliance with the European Union’s General Data Protection Regulation.
