The Securities and Exchange Commission’s announcement of insider trading charges against a former information technology administrator for cybersecurity company Palo Alto Networks Inc. raises questions about what, if anything, in-house leaders can do to prevent similar incidents. 

In the Palo Alto Networks case, the IT staffer in question, Janardhan Nellore, allegedly accessed “highly confidential” financial records with his employee credentials, then shared the insider information with four friends. Nellore pleaded guilty Wednesday to conspiracy to commit securities fraud before a federal judge in San Jose in a related criminal case.
