TAC InfoSec Limited (NSE: TAC) reported a sharp acceleration in profitability for the first quarter of fiscal 2027, with profit after tax surging 137% year-on-year.

The Mumbai-listed cybersecurity firm, which operates globally under the TAC Security brand, also announced total income rose 97% compared to the same period last year, reflecting robust adoption of its AI-powered security solutions.

In a significant forward-looking statement, the company set revenue guidance of approximately INR 100 crore for the full fiscal year 2027.

This target underscores management’s confidence in sustaining the current growth trajectory amid increasing enterprise demand for automated threat detection and response systems.

The results stand in contrast to the broader Indian IT sector, which faces structural headwinds and mixed earnings forecasts for the start of fiscal 2027.

While large-cap peers like Tata Consultancy Services have reported steady but moderate growth, niche cybersecurity players like TAC InfoSec are capturing disproportionate gains from the accelerating shift toward AI-integrated security infrastructure.
