Summary · why it matters

Thailand Securities Depository Company Limited, or TSD, has confirmed that all shares and funds in investor accounts remain fully intact following a personal data leak affecting approximately 200,000 accounts out of a total of 5 million service users. Unauthorized access to the TSD Investor Portal system was detected late at night on July 25, 2026. The leaked data includes full names, dates of birth, national ID numbers, addresses, phone numbers, emails, as well as securities company names with trading account numbers, and bank names with bank account numbers. TSD immediately blocked access to the system and enhanced security measures with multi-factor authentication and AI technology to scan for vulnerabilities. The company stressed that the system is only an online information viewing channel, not a stock trading system. Securities holding data and trading history were not affected. All assets and investments remain safe. However, TSD warned that criminals may use the leaked phone numbers or emails for scams, and recommended six ways to prevent cyber threats, such as not clicking fake links, verifying official emails only from SETContactCenter@set.or.th, not falling for impersonations requesting personal data or passwords, changing passwords regularly, and frequently checking for account irregularities. If any damage is found, contact the TSD Contact Center at the aforementioned email or at 0-2009-9999.

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.
