Tesla's security division has come under scrutiny during the past year, as two of the company's former security employees have filed whistleblowing tips with the Securities and Exchange Commission alleging that Tesla hacked employee devices and did not disclose to shareholders the theft of raw materials.

Tesla has denied the former security employees' claims.

The company is known for a high rate of turnover among executives and senior-level employees. This year, Tesla has lost its CFO, vice president of global recruiting, and general counsel.
