## Value props — 58, Fair

This category assesses whether the title, subtitle, and hero communicate the product’s value.

### Headline

**“An AI defense system for cyber attack”**

**Subhead:** “The power dynamic just shifted back to the defenders.”

### Working

- Names the AI and cyber-defense category quickly.
- Uses an emotional defender angle in the subhead.
- Stays short, confident, and jargon-free.

### Could improve

- Names no concrete outcome or mechanism.
- Provides zero numbers or proof in the fold.
- Uses hero art decoratively rather than demonstrating the product.

### Value-proposition ranking

1. Cynet — 78
2. Abnormal AI — 78
3. SentinelOne — 72
4. NebuSec — 58
5. Darktrace — 42
6. CrowdStrike — 42

## CTA — 62, Fair

This category assesses CTA copy, size, verb, and perceived cost. NebuSec’s shown primary CTA is **“Book a demo.”** The report identifies these problems:

- Demo booking feels costly.
- The hero button is low-contrast and small.
- There is no low-friction alternative path.
- The navigation button outweighs the hero button.

![NebuSec CTA capture](https://zlfyzdmohcskkucuunmk.supabase.co/storage/v1/object/public/sites/growth-score/site/nebusec.ai.jpg?v=2026-09-20T05%3A16%3A12.139%2B00%3A00)

The comparison captures show these CTA labels from other named companies: SentinelOne, **“Free Platform Demo”**; Cynet, **“Request a Demo”**; Darktrace, **“Get a demo”**; Abnormal AI, **“See It in Action”**; and CrowdStrike, **“Register now.”**

### CTA ranking

1. SentinelOne — 74
2. Cynet — 72
3. Darktrace — 68
4. Abnormal AI — 68
5. CrowdStrike — 66
6. NebuSec — 62

## Mobile web — 62, Fair

This category evaluates the phone experience.

![Mobile web annotations on the mobile capture](https://zlfyzdmohcskkucuunmk.supabase.co/storage/v1/object/public/sites/growth-score/site/nebusec.ai-mobile.jpg?v=2026-09-20T05%3A16%3A12.139%2B00%3A00)

1. **Hero “Book a demo”:** A translucent gray pill blends into the sky, sits at the viewport’s bottom edge, has low contrast, and is not full-width.
2. **Planet hero image:** A decorative sphere consumes the top half of the fold, pushing the headline and CTA to the very bottom.
3. **Subhead over starfield:** Light gray text over a busy star background reduces legibility of the value statement.

## Information hierarchy — 78, Fair

This category evaluates whether the design helps or inhibits the page’s message.

![Information hierarchy annotations on the desktop capture](https://zlfyzdmohcskkucuunmk.supabase.co/storage/v1/object/public/sites/growth-score/site/nebusec.ai.jpg?v=2026-09-20T05%3A16%3A12.139%2B00%3A00)

1. **Hero “Book a demo”:** A dark button on the dark sky nearly vanishes, so the primary action fails the one-second find test.
2. **Navigation “Book a demo”:** A white navigation button outweighs the hero CTA, creating two competing visual weights for the primary action.
3. **Dimmed navigation links:** Product, Security Audit, Research, and About use low opacity and read as disabled rather than navigable.
