Not everyone was worried, however, by Halock's findings. "I'm not very alarmed by what they found," Marc Gaffan,
founder of Incapsula, a cloud security company, said in an interview. "Email encryption is overkill."

"The usability aspects around email encryption are not trivial," Gaffan said.
Encrypting email is only a small part of the problem, he continued. "The real problem is what happens to that email when it hits the university."
"It's like keeping a key in the lock," Gaffan said. "The fact that the door has a lock on it doesn't protect it if the key is in the lock and anyone can unlock it."
