iPhones made up 73% of activated smartphones in companies using Good Technology's enterprise mobility products, while Android made up just 25%.
The iPhone is the most popular smartphone in the enterprise by nearly a three-to-one margin, according to data from Good Technology's quarterly Mobility Index Report for Q4 of 2014.
The company, which provides mobile device services to 6,200 organizations worldwide, including half of the Fortune 100, publishes a broad look at market share trends and app usage stats every quarter.
Last quarter, the company found that iOS activations accounted for 73% of all devices activated in the quarter, up from 69% in the quarter previous. It's likely that the uptick can be attributed to the iPhone 6, which was launched at the end of Q3. Android saw its activation share drop from 29 to 25%, exactly mirroring Apple's 4% growth. Windows Phone and Microsoft Surface have remained flat across the last six quarters, accounting for a paltry 1% of activations.
The iPhone 6 and 6 Plus were responsible for 30% of all activations in Q4, with the 6 and 6 Plus seeing a 77/23% split between the two devices.
In highly regulated industries like the legal and financial services sectors, iOS was the clear winner, making up an impressive 95% and 81% of activations in those verticals, respectively.
Android saw higher adoption in industries with "less stringent regulatory compliance restrictions." For example, 45% of activated devices were running Android in High Tech, while manufacturing and transportation saw adoption rates of 39 and 35%.
Recent high-profile hackings like the one at Sony Pictures, where many corporate email messages were leaked to much embarrassment, have clearly had an impact on employee app usage.
Secure browsers made up 27% of all browsers deployed by organizations, with secure instant messaging apps close behind. On the iPhone, secure IM and secure browsing apps are by far the most popular apps, while on tablets, document editing and access were the most popular app types.
The company says that tablet users are focused on document-oriented tasks, while on smartphones, quick access to information and communication is highly valued.
Secure, ephemeral messaging apps like Cyber Dust, from billionaire entrepreneur Mark Cuban, have seen huge increases in usage. Cuban's own troubles with the SEC, where his digital messages were used against him in court, drove him to work on the app. With it, he can make secure digital communications that expire, meaning they theoretically can't be used in any sort of legal proceeding. Cuban says he negotiated some of his Shark Tank contract over the platform, concerned about details being leaked in the press after the Sony Pictures hack.
Kaspersky Lab offers a secure browser for the iPhone and iPad called the Kaspersky Safe Browser. It includes technology to block malicious links and phishing websites, updated from Kaspersky's database of dangerous websites.
