Summary · why it matters

The Stock Exchange of Thailand must urgently restore confidence after Thailand Securities Depository Company Limited, or TSD, admitted that personal data of users of the TSD Investor Portal system has been further leaked following an unauthorised access incident. The affected data includes full name, date of birth, national ID number, address, phone number, email, securities company name, securities trading account number, bank name, and bank account number. Although TSD confirmed that securities holding data and securities trading transaction data have not been found to be affected, and there is no confirmation that the data has been used to cause harm, this incident has severely shaken confidence in the data protection standards, supervision, and risk management of Thailand's capital market. TSD has apologised and pledged to urgently improve system security measures, while warning investors to be cautious of emails, SMS messages, or phone calls impersonating various organisations to trick them into revealing personal data, passwords, or OTP codes, and recommending that they change passwords regularly, avoid reusing passwords, and regularly check for account irregularities.

Commvault Enables FedRAMP High Cloud for Federal Agencies

Commvault Systems has enabled its managed service provider partners to deliver FedRAMP High Authorized Commvault Cloud for Government services to U.S. federal agencies and defense contractors, broadening the company's public sector reach. The move lands on a stock with a 7 day share price return of 10.29% and a 90 day share price gain of 11.67%, though its 1 year total shareholder return is down 23.35% while the 3 year total shareholder return is up 111.68%. The most followed valuation narrative puts fair value at $161.15 against a last close of $145.21, implying roughly 10% upside, and rests on analyst expectations of about 10.6% annual revenue growth, profit margins rising toward 9.8%, and an 8.85% discount rate. That story leans on recurring SaaS economics, including 63% SaaS ARR growth, a 45% increase in multi-product customers, and 125% SaaS net dollar retention. A contrasting read notes the stock trades at a P/E of 88.1x versus 30.5x for the wider US Software group and a fair ratio of 38.7x, signaling valuation risk if sentiment cools.

Varonis Systems Launches Data Lifecycle Management Capability

Varonis Systems, Inc. launched Varonis Data Lifecycle Management, a new capability that automatically identifies and remediates redundant, obsolete, and trivial data across enterprise environments using its existing Data Security Platform. The launch ties data cleanup directly to sensitivity, access, and activity context, aiming to reduce storage waste, improve AI output quality, and help organizations address compliance exposures from scattered sensitive information. The DLM tool stacks on top of Varonis Atlas, the AI security platform that went generally available in March 2026, which targets discovery, posture management, and runtime protection for AI workloads. Together, Atlas and DLM broaden Varonis' role from guarding unstructured data to governing how that data is stored, used, cleaned up, and exposed across Snowflake, Claude, Cursor, and other cloud and AI partnerships. Varonis Systems' narrative projects $1.1 billion revenue and $120.7 million earnings by 2029, yielding a $50.68 fair value, an 8% upside to its current price, while the most pessimistic analysts were already modeling about US$1.0 billion of 2029 revenue.
