Palantir stock: why the NGC2 security loophole may be more than just a hiccup

by October 4, 2025
by October 4, 2025

Palantir Technologies Inc (NYSE: PLTR) slipped more than 4.0% on Friday following reports of serious cybersecurity issues in its battlefield communication system co-developed with Anduril.

An internal US Army memo flagged the NGC2 platform this morning as posing “very high risk” due to vulnerabilities that could allow adversaries undetectable access.

Gabrielle Chiulli – the Army’s chief of technology – cited weak access controls and unvetted third-party applications.

Note that Palantir stock, nonetheless, remains up a whopping 175% versus its year-to-date low.

Why is the Army memo super concerning for Palantir stock

PLTR stock is losing ground this morning mostly because the company’s involvement in that $100 million prototype contract has now come under scrutiny – raising concerns about its defense tech credibility.

This aforementioned Army memo strikes right at the heart of Palantir’s value proposition: secure, mission-critical data platforms.

NGC2 is built for battlefield intelligence. So, it makes sense for investor confidence in Palantir’s core competency to receive a major blow if it’s found to lack basic access restrictions and audit trails.

The revelation that integrated apps hadn’t undergone proper security vetting – with one containing 25 high-severity code flaws – adds to the alarm.

While Leonel Garciga, the US Army’s chief of information ,framed the memo as part of a broader vulnerability triage process, the damage to perception is real.

PLTR reputation as a trusted defense partner hinges on airtight security – and the memo suggests cracks in that foundation.

Should you buy the dip in PLTR shares today

Palantir shares already trade at an egregiously stretched valuation, with investors pricing in near-perfect execution across defense, artificial intelligence (AI), and commercial verticals.

At a forward price-to-earnings (P/E) ratio of about 425, the data analytics giant really has little to no room for operational missteps.   

A cybersecurity lapse of this magnitude doesn’t just dent short-term sentiment – it may just end up challenging the long-term thesis.

The idea that any authorized user could access all data regardless of clearance, with no logging, is antithetical to Palantir’s brand.

Given that it’s a business that touts its platforms as secure and scalable, this kind of exposure could trigger a deeper, prolonged sell-off in PLTR shares.

Until Palantir demonstrates robust remediation and transparency, buying the dip looks premature.

Wall Street recommends caution on Palantir Technologies

Palantir stock’s stumble comes at a time when defense-tech is under heightened scrutiny.

While the company remains a key player in AI and battlefield analytics, investors should monitor how it responds to this setback.

Execution risk is now front and center – and in a premium-priced stock, that’s a dangerous place to be.

Note that Wall Street also recommends caution in buying PLTR shares on the dip.

The consensus rating on the Denver-headquartered firm currently sits at “hold” only, with the mean target of about $157 indicating potential downside of some 12% from here.
