What users can and can't do using the API
While email integration carries the advantage of easy configuration, a direct integration between your ticketing system and Dark Web ID solution avoids any issues that may occur with email delivery and processing. Using Dark Web ID’s compromise API, you’ll also have easier access to the metadata of compromises rather than parsing text from an email notification.

Fighting climate change

Fighting climate change

The environmental benefits of our G-Cloud Service provision are substantiated by Microsoft’s own studies and commitments towards climate change.
A 2018 study found that using the cloud platforms can be up to 93% more energy efficient and up to 98% more carbon efficient than on-premises solutions.

Real sustainability requires solutions that address wastefulness at every level of a business. Hosting on the cloud is more environmentally friendly and results in less of a carbon footprint.
Cloud infrastructures support environmental proactivity, powering virtual services rather than physical products and hardware, and cutting down on paper waste, improving energy efficiency, and (given that it allows employees access from anywhere with an internet connection) reducing commuter-related emissions. Independent reports predict that data centre energy consumption would drop by 31% from based on the adoption of cloud computing and other virtual data options.
Covid-19 recovery

Covid-19 recovery

As a member of the COVID-19 High Performance Computing Consortium, Microsoft is helping researchers accelerate their understanding of the virus and the development of treatments and vaccines through two major initiatives; HPC Consortium and AI for Health.
The COVID-19 HPC Consortium encompasses computing capabilities from some of the most powerful and advanced computers in the world. Microsoft hope to empower researchers around the world to accelerate understanding of the COVID-19 virus and the development of treatments and vaccines to help address infections. Consortium members manage a range of computing capabilities that span from small clusters to some of the very largest supercomputers in the world.
AI for Health is a new $60 million, five-year philanthropic program from Microsoft, created to empower non-profits, researchers, and organizations tackling some of the toughest challenges in global health. Microsoft are providing access to AI and expertise in these areas; Accelerating medical research to advance the prevention, diagnoses, and treatment of diseases, increasing our shared understanding of health and longevity to protect against global health crises, reducing health inequity and improving access to care for underserved populations and supporting fundamental research capabilities, including data collaboratives and differential privacy.


The primary benefits of Microsoft's cloud services are the transfer of ownership of compliance and maintenance of cloud infrastructure and its security and that IT Managers and business owners no longer need to be concerned about those elements of their IT systems once in a Microsoft cloud platform. This has a massive positive impact on wellbeing of employees within organisations across the world.
