Addressing AI's Double-Edged Impact on SaaS Security
Article content
Agentic AI offers powerful productivity gains but also introduces new risks. While these agents streamline workflows and enhance efficiency, they expand the attack surface by leveraging the same integration mechanism used by SaaS-to-SaaS integrations. AI-embedded SaaS tools and autonomous systems operating with excessive permissions via longstanding OAuth connections magnify the SaaS-to-SaaS integration blindspot.
Article content
Obsidian's foundational Knowledge Graph provides a unique advantage in solving this problem. By unifying SaaS, endpoint, network, and identity data, Obsidian delivers the contextual insight necessary to understand not just what AI agents are accessing, but how that access fits within the broader ecosystem of application relationships and user behaviors.
Article content
The platform's deep visibility into application usage—enriched with workload context and in-app activity monitoring—enables Obsidian to detect subtle OAuth token anomalies that signal malicious or compromised AI agents. This intimate understanding of SaaS interconnections is exactly what's required to secure environments where autonomous agents have become new actors.

Building on this foundation, Obsidian is partnering with Fortune 500 customers to bring to market enterprise-tested solutions to safely and rapidly adopt Agentic AI.

Baseball Commissioner Rob Manfred confronted by Bryce Harper during meeting, AP source says
Philadelphia Phillies' Bryce Harper reacts after hitting a home run against Boston Red Sox pitcher Lucas Giolito during the first inning of a baseball game Wednesday, July 23, 2025, in Philadelphia. (AP Photo/Matt Slocum) CHICAGO — Baseball Commissioner Rob Manfred and Philadelphia Phillies star Bryce Harper had a spirited exchange during a question-and-answer session between the commissioner and the team, according to a person with direct knowledge of the conversation. The person spoke to the AP on Monday on condition of anonymity because of the sensitivity of the situation. Phillies slugger Nick Castellanos previously confirmed some details from the meeting in interviews with The Bandwagon and ESPN. Speaking before Philadelphia's game at the Chicago White Sox, Harper did not dispute the published descriptions of his confrontation with Manfred. 'I won't be getting into the details of what happened or how I felt or anything else like that,' Harper said. 'I don't think it does any good for anybody for that to happen. So, for me, I just, you know, trying to worry about baseball, trying to worry about everything in here.' Manfred met with the Phillies and Red Sox during their series last week in Philadelphia. The session with the Phillies lasted more than an hour. Manfred spoke with the NL team about the media landscape and working together to grow the sport, according to the person with knowledge of the conversation. At some point, Harper told Manfred if he was there to talk about a salary cap, he could 'get the (expletive) out' of the clubhouse. Baseball's collective bargaining agreement expires Dec. 1, 2026, and some players are concerned about a possible management push for a cap. A spokeswoman for the Major League Baseball Players Association declined comment on Monday night. Harper is a two-time NL MVP and one of the game's marquee names, making his conversation with Manfred more noteworthy. The eight-time All-Star agreed to a $330 million, 13-year deal with the Phillies in February 2019. 'Obviously, I don't want that to happen in those meetings,' Harper said. 'I don't want those things to be out there. I think, you know, when we have meetings with the commissioner or anybody else that comes to our clubhouse, those are good meetings to have.' Manfred and some owners have cited payroll disparity as one of baseball's biggest problems, while at the same time MLB is working to address a revenue decline from regional sports networks. Unlike the NFL, NBA and NHL, baseball has never had a salary cap because its players staunchly oppose one. Manfred has been meeting with teams more often since he said in the aftermath of baseball's March 2022 labor agreement that he needed to work on his relationship with players. 'When I talk to the players, I don't try to convince them that a salary cap system would be a good thing,' Manfred said during the All-Star break. 'I identify a problem in the media business and explain to them that owners need to change to address that problem. I then identify a second problem that we need to work together and that is that there are fans in a lot of our markets who feel like we have a competitive balance problem.' Asked for his argument against a salary cap and why it's such an important issue for players, Harper responded: 'I don't want to get into details as of right now.' He also said he planned to remain vocal about labor issues behind closed doors — just as he has done in the past. 'I've talked labor and I've done it in a way that I don't need to talk to the media about it,' he said. 'I don't need it out there. It has nothing to do with media or anybody else. It's what we can as players and owners and everybody else can come together to try to make this game great.' ___ AP MLB: Jay Cohen, The Associated Press

U.S. Treasury says it will borrow $1-trillion in third quarter to rebuild cash balance
The U.S. Treasury said on Monday it expects to borrow US$1.007-trillion in the third quarter partly to replenish its cash balance that dwindled during the latest debt ceiling episode. The figure was US$453-billion higher than its April estimate primarily due to the lower beginning-of-quarter cash balance and projected lower net cash flows. The third-quarter financing projection assumes cash of US$850-billion at the end of September for the Treasury, the department said in a statement. Much higher borrowing in the third quarter were needed to rebuild the Treasury's cash balance following President Donald Trump's tax and spending bill being signed into law on July 4. The debt ceiling increased by US$5-trillion to US$41.1-trillion following the spending legislations enactment. The Treasury's cash had dropped to US$313-billion on July 3, data from money market research firm Wrightson ICAP showed. Trump's 'big, beautiful' bill set to further tarnish U.S. Treasuries' lustre overseas 'These [financing estimates] are in line with our projections and should not be a surprise to the markets since the increased financing need is almost all due to the shortfall in cash balances on September 30, which was a function of the debt limit,' said Kim Rupert, managing director, global fixed income analysis at Action Economics, The Treasury also said it expects to borrow US$590-billion in the fourth quarter, as it projects a cash balance of US$850-billion at the end of December. In the second quarter, the Treasury said it borrowed US$65-billion in privately-held marketable debt, ending the period with a cash balance of US$457-billion. In April, Treasury had estimated borrowings of US$514-billion and assumed an end-of-June cash balance of US$850-billion. The Treasury will unveil details of it borrowing estimates for the quarter on Wednesday when it announces its financing plans. It is widely expected that the Treasury will maintain current auction sizes for notes and bonds and will likely keep them steady for some time. Investors will be looking for guidance as to how long the Treasury can hold off not raising the size of the debt auctions used to fund the ballooning U.S. budget deficit.
