Security operations are becoming more complex to manage internally. Environments change quickly, and threats continue to evolve. As a result, many organizations are reviewing methods for protecting critical systems and sensitive data.
This shift is reflected in the scale of cybercrime and the growing role of external security partners. Cybersecurity Ventures predicts global cybercrime damages will reach $12.2T annually by 2031[1]. At the same time, Fortune Business Insights projects the managed security services market to grow to $104.66B by 2034[2]. Together, we can see why protection outsourcing is becoming a core part of enterprise security strategies.
