Excite Technology Services Ltd (ASX: EXT)

Analysts at Red Leaf Securities are recommending this small cap ASX share as a buy this week.

It is a cybersecurity company offering comprehensive cybersecurity services, including threat prevention, managed cloud and IT services, specialist digital forensics, incident response, forensic investigations, and accredited training.

Red Leaf thinks its shares are undervalued, especially given its record month in September. It said:

EXT offers cybersecurity services, including threat prevention. We like its outlook in response to strategic acquisitions, improving financial performance and growth prospects. It achieved record monthly sales of $7.14 million in September 2025. The stock appears undervalued relative to its growth potential. With an expanding product suite and broader market reach, EXT is well-positioned for scalable growth, making it an appealing opportunity for investors seeking exposure to the cybersecurity and technology sector.

Red Leaf Securities thinks it could be a top pick for investors with a high tolerance for risk. It said:

FCT is a global software company. The company's recent capital raising of $2.85 million is aimed at accelerating its shift to artificial intelligence-powered compliance management, leveraging its user base of more than 150,000 to unlock potential annual recurring revenue. On top of the capital raising, the company secured a $2.5 million loan facility, which further enhances financial flexibility amid supporting initiatives. Recently, trading below book value, FirstWave combines value and growth potential. The stock was trading at 1.2 cents on October 16.
