Profits are clear, faster growth is not

01 Running thesis

A steady compounder needs proof

Qualys is still a clean execution story. It beat Q1 expectations, raised full-year revenue guidance, and kept showing strong profit discipline. That fits its long-running pitch: one cloud platform can help customers find cyber weak spots, rank the danger, and fix the most urgent ones.

The better news is under the surface. Qualys disclosed that customers using its newer Enterprise TruRisk Management, or ETM, and Cybersecurity Asset Management, or CSAM, products had 107% net dollar expansion. That means this group spent 7% more than a year ago after renewals, upgrades, and downgrades. The full company was only at 104%, so the newer platform products look stickier than the average account.

The problem is scale. Total company growth is still modest, with full-year revenue guidance pointing to 8% to 9% growth. The company-wide expansion rate has not yet broken out of the 104% area. Until that changes, the market is being asked to believe that a good cohort will become large enough to pull the whole company faster.

Competition also got harder. Qualys names Wiz as a competitor, and Wiz was acquired by Google in March 2026. That puts a hyperscaler, meaning a giant cloud platform owner, more directly into Qualys' cloud security market. The stock can work if platform adoption and the partner channel keep building, but the growth proof is not complete.

May 2026Qualys' 10-Q named Wiz as a competitor and noted that Google acquired Wiz in March 2026. That raises the cloud security threat for TotalCloud CNAPP.
May 2026Q1 revenue grew 10% to $175.6 million, and Qualys raised full-year revenue guidance to $721 million to $727 million. The first ETM and CSAM cohort disclosure showed 107% net dollar expansion.
Nov 2025Q3 2025 was another beat-and-raise quarter. Partner-led revenue reached 50% of total revenue, and the company showed progress in federal deals after FedRAMP High authorization.
Aug 2025Net dollar expansion improved to 104% from 103%, the first move up in several quarters. Qualys also raised 2025 guidance and introduced a more flexible platform pricing model.
May 2025Q1 2025 reduced near-term execution risk with better revenue and higher EPS guidance. Partner-led revenue grew 19%, though total net dollar expansion stayed at 103%.
Feb 2025The 2025 guide pointed to slower revenue growth of 6% to 8%, and the Chief Revenue Officer departure added sales execution risk. Net dollar expansion stayed at 103%.
Nov 2024Q3 2024 improved the setup after a beat-and-raise quarter and a rebound in calculated billings growth to 14%. Partner-led revenue reached 47% of total revenue.
Aug 2024The initial thesis framed Qualys as a platform consolidation story with strong products but soft upsell execution. Net dollar expansion had fallen to 102%, and management had cut full-year revenue guidance.
02 Business model

Subscriptions built around risk

Qualys makes money by selling subscriptions to its Enterprise TruRisk Platform. Customers pay for modules that cover jobs like vulnerability management, patching, asset tracking, cloud security, and risk measurement. The more modules a customer uses, the more valuable the platform should become.

The model works best when Qualys lands with its core vulnerability product, then adds other tools over time. That is why net dollar expansion matters. If existing customers keep spending more, Qualys can grow without needing every dollar to come from new customers.

The go-to-market mix is shifting. Partner-led revenue reached 52% of total revenue in Q1 2026, up from 49% a year earlier, and grew 17%. Direct revenue grew 3%. This partner motion can widen reach, but it also makes sales leadership and partner focus important.

Where it can break is in the core market. Vulnerability management is more mature and can face pricing pressure. If newer products fail to sell into the installed base, Qualys may stay a profitable but slower-growth software company.

03 Product portfolio

From finding bugs to fixing them

Cash cow

VMDR with TruRisk

Vulnerability Management, Detection and Response is the core product. It helps customers find security flaws, rank them by risk, and decide what to fix first.

Growth engine

Patch Management

Patch Management helps automate the fix after a weakness is found. It supports the move from alerting customers to helping them take action.

Growth engine

CSAM with EASM

Cybersecurity Asset Management shows customers what technology assets they have, including internet-facing assets. Its 107% cohort expansion with ETM is an early sign that platform adoption can improve spending.

Option

TotalCloud CNAPP

TotalCloud is Qualys' cloud security product. It is strategically important, but competition is rising after Google's acquisition of Wiz.

Growth engine

Enterprise TruRisk Management

ETM helps security teams turn many alerts into a clearer risk score and action plan. The product is central to Qualys' platform upsell story.

Option

Agent Vail

Agent Vail is part of ETM and is now generally available. It aims to validate whether a flaw can be exploited and then help automate remediation.

Option

Q-Flex pricing

Q-Flex is a platform pricing model meant to let customers use Qualys units across modules. Qualys plans a full go-live for select customers and partners later in 2026.

05 Risk factors

What could break the thesis

Cloud security gets tougher after Wiz

High impact · Medium odds

Qualys already competes with large security platforms. Google's acquisition of Wiz adds a cloud giant with large distribution and deep funding. This could hurt TotalCloud CNAPP win rates, lengthen sales cycles, or pressure prices.

We watchWatch management comments on TotalCloud CNAPP win rates, pricing, and deal timing after the Wiz deal.

The platform cohort stays too small

High impact · Medium odds

The 107% ETM and CSAM expansion rate is encouraging, but the full company remains at 104%. If the stronger cohort is not large enough, it will not move total growth. The reacceleration story needs the company-wide number to rise.

We watchWatch whether total net dollar expansion moves above the 104% to 105% range.

Growth stays in high single digits

Medium impact · High odds

Full-year revenue guidance points to 8% to 9% growth. That is not broken, but it is slower than investors usually want from a cybersecurity software company. A mature core market makes cross-sell execution more important.

We watchWatch revenue guidance, billings growth, and growth in customers spending $500,000 or more.

Sales leadership remains unsettled

Medium impact · Medium odds

Qualys still lacks a permanent Chief Revenue Officer. That matters during a partner-first shift because the company must balance direct sellers, partners, and platform pricing. A long delay could create confusion in the field.

We watchWatch for the hiring of a permanent CRO and any change in direct versus partner growth.

Budget caution slows upsells

Medium impact · Medium odds

Management continues to cite macro volatility. When security budgets are tight, customers may delay adding new modules even if they renew core products. That would keep expansion rates flat.

We watchWatch net dollar expansion, gross retention, and management comments on sales cycles.
06 Quick answers

In one breath

What does Qualys do?

Qualys sells cloud-based cybersecurity software. Its tools help companies find assets, detect security weaknesses, rank risk, and fix the most urgent problems.

Why does net dollar expansion matter for Qualys?

Net dollar expansion shows whether existing customers spend more over time after renewals, upgrades, and downgrades. Qualys' total rate was 104% in Q1 2026, while ETM and CSAM customers were at 107%.

Is Qualys growing fast?

Qualys is growing, but not at a high-growth software pace. Q1 revenue grew 10%, and full-year guidance points to 8% to 9% revenue growth.

What is the biggest risk for Qualys?

The biggest risk is that newer platform products do not grow fast enough to offset a maturing core vulnerability market. Competition in cloud security also increased after Google bought Wiz in March 2026.
