What Is Integrated Cloud Email Security (ICES) And Why Do You Need It?
KnowBe4, Tuesday, March 17th, 2026
Integrated cloud email security (ICES) is a term coined by industry analyst, Gartner, in their 2021 Market Guide for Email Security.
The guide was reissued in 2023 and stated that 'by 2025, 20% of anti-phishing solutions will be delivered via API integration with the email platform, up from less than 5%' at the time of publication'.
Using machine learning, natural language understanding (NLU), and natural language processing (NLP), an ICES solution goes beyond blocking known threats to detect zero-day and emerging attacks, as well as detecting text-based attacks that leverage social engineering. These solutions can also educate employees in real time.
