Sponsored by Armorblox, Enterprise Strategy Group (ESG), a leading research and advisory firm, conducted a research survey of 490 IT and security professionals with a focus on the challenges organizations face in securing the abundance of communication and collaboration tools used today.

Despite maturity, email security still has significant weaknesses, with 38% of respondents believing email is the channel most vulnerable to threat actors. This emphasizes the high level of risk associated with email communication, and the continued vulnerabilities of legacy security tools when it comes to protecting against sophisticated threats.
