Cybersecurity Google Ads CPC Benchmarks: What You Actually Pay by Category

If you look up cybersecurity Google Ads CPC, you will find one number: $35.80, quoted as the average cost per click for cybersecurity. It sits on a single agency page and everything else repeats it.

I went looking for where it came from, because it did not match anything I have seen running paid search in this category. Then I built the distribution properly.

Across 15 cybersecurity categories, the estimated cost of a click runs from $20 to $189. Only 2 of those categories price entirely below $35.80. Penetration testing runs 3 to 5 times above it.

Here is the data, how I produced it, and the part that matters more than any individual number.

How I got these numbers

Two sources, joined.

Google Keyword Planner gives a top-of-page bid range for any keyword. That is Google’s estimate of what you would need to bid to appear at the top of the page. I pulled 36 seed terms across 15 categories, US, English, Google Search.

The problem is that a top-of-page bid estimate is not a cost per click. It is what Google thinks you would have to bid, and actual CPC generally lands below it. Publishing those figures unadjusted would repeat the exact error that makes the $35.80 number useless: presenting one kind of number as though it were another.

So I calibrated the estimates against real spend. Across 5 B2B accounts I manage, I pulled every keyword with 30 or more clicks over 90 days, took its actual average CPC, then pulled Google’s estimate for that same keyword text and compared the two. 249 keywords matched.

That gives a conversion factor between what Google estimates and what advertisers actually pay.

The calibration, and why raw Keyword Planner data misleads

The headline result:

Three things worth pulling out of that table.

Google’s high estimate runs roughly 2x above what non-brand keywords actually cost. Not 10x, not identical. If you have been planning budgets off Keyword Planner’s upper number, you have been overestimating by about half.

Brand keywords behave completely differently, at 17%. That is Quality Score doing its work: when your ad, keyword and landing page all match a search for your own company, you pay a fraction of what the auction would otherwise demand. Anyone quoting a blended figure across brand and non-brand is publishing an artifact of their own account mix.

This is why the categories below use 56% rather than 35%. Category terms like “penetration testing services” are non-brand by definition. Applying the blended number would understate them by roughly 40%, and understating is the more dangerous direction when someone is sizing a budget.

For the record, 59% of keywords landed between Google’s low and high estimate, and actual CPC ran at a median 152% of the low estimate. Treat the low figure as a floor and the high figure as a ceiling about twice reality.

Cybersecurity CPC by category

15 categories, 36 seed terms. Estimated actual CPC is Google’s high top-of-page bid multiplied by 0.56.

Total search volume across those 36 terms is roughly 70,000 queries a month, which is worth sitting with on its own. Cybersecurity is an expensive category rather than a large one.

Five things the distribution shows

1. Pentest is the most expensive category, and it is not close

I expected SIEM or EDR to top this list. Enterprise budgets, long payback tolerance, entrenched vendors. That was wrong.

Penetration testing runs $123 to $189 a click, roughly 60% above the next category. The reason is likely urgency rather than budget. Someone searching for a pentest usually has a customer contract or an audit deadline forcing the purchase, and a small vendor set is competing for a scarce, genuinely ready buyer.

If you sell pentest or PTaaS, your paid search economics are harder than any other corner of security, and your account has less room for waste than anyone else’s.

2. Volume and price are close to unrelated

IAM has 14,100 monthly searches at $43 to $58. Security awareness has 14,800 at $48. Compliance and SOC 2 has 850 searches at up to $147.

The two highest-volume categories here are mid-priced, and one of the most expensive is among the smallest. Whatever sets these prices, simple demand is not it.

3. The public $35.80 figure sits below almost the entire market

The lowest estimated actual CPC in the dataset is $20, at the very bottom of zero trust and SASE. Only 2 of the 15 categories price entirely below $35.80, zero trust / SASE and API security, and 12 of 15 top out at $56 or higher.

Plan against $35.80 and you will size your budget for roughly a third of the clicks you actually get.

4. The cheap corners are the newest categories

Zero trust and SASE at $20 to $33, API security at $31, AppSec starting at $22. These are the categories where the buying process is least established, which means less competition and more education required after the click.

Cheap traffic in an unformed category is not automatically a bargain, and it is where a small budget can still buy meaningful presence.

5. Every figure here is a category head term, which is the expensive way in

Everything above prices the most competitive query in each category. Comparison terms, alternative terms and requirement terms sit well below these numbers and much closer to a decision. That gap is the most useful thing on this page for a company with a $6,000 monthly budget.

Finding those terms is not guesswork. They are sitting in your own search terms report, in the queries that already reached you through broader matching, and the method for extracting them systematically is the n-gram analysis I walk through separately.

One caution specific to this category. The same adjacency that makes comparison terms cheap also makes them easy to over-block. Security accounts often negate vs wholesale to cut informational traffic, which removes every competitor comparison query in the account at once. In a category where head terms cost $150, that is an expensive tidiness.

Why the five most expensive categories cost what they do

Price in an auction is set by how many well funded bidders think a click is worth having, filtered through Ad Rank. Here is what appears to be driving each of the top five.

Pentest / PTaaS: $123 to $189

Deadline-driven demand meeting a small vendor set. Almost nobody searches for a penetration test out of curiosity. They search because an enterprise customer’s security review requires one, a SOC 2 or PCI audit is scheduled, or a board asked after an incident. The buyer arrives with a date attached, which makes them unusually likely to purchase and unusually insensitive to price.

Supply is also thin. Delivering pentest work needs qualified humans, so the vendor set cannot expand the way a software category can. A small number of firms bid hard against each other for a scarce, ready buyer, and 3,970 monthly searches is not much volume to fight over.

The consequence for anyone selling here is uncomfortable. Your account has the least tolerance for waste in security, because a single wasted click costs more than a whole lead does in most categories.

Compliance / SOC 2: $59 to $147

The widest range in the dataset, and the reason is competitor bidding. This category has absorbed enormous venture funding, and the well known players have both the budget and the strategic reason to defend every query. When several funded companies each decide they cannot afford to lose a compliance search, the auction stops reflecting the value of the click and starts reflecting a standoff.

Note the volume: 850 searches a month, the smallest in the top five. This is the clearest case in the data of price being set by competitor behaviour rather than by demand.

It is also where the gap between head terms and alternative terms is widest. A “[incumbent] alternative” search is a company actively looking to switch, and it prices far below the category head.

SIEM / EDR / XDR: $52 to $113

Enterprise deal sizes and long payback tolerance. A SIEM contract can run into seven figures across a multi-year term, so a buyer with a nine-month CAC payback tolerance can rationally outbid a startup by an order of magnitude and still be right.

This is the category where a Series A company is most clearly competing against balance sheets rather than relevance. It also carries heavy practitioner search traffic, since security engineers research SIEM tooling constantly without any authority to buy, which means the negative keyword layer matters more here than almost anywhere.

MDR / MSSP: $43 to $87

Services pricing, with a longer commitment behind it. Managed detection buyers are usually outsourcing a function they cannot staff, which makes the decision closer to a hire than a purchase and the contract stickier once won.

Higher lifetime value justifies higher acquisition cost, so bidders tolerate expensive clicks. The saving grace is 3,440 monthly searches, which is more room than pentest or compliance offer.

Cloud / CNAPP: $64 to $81

The tightest range in the top five, which itself says something. A narrow spread usually means a mature auction where bidders have converged on similar valuations rather than one where somebody is bidding emotionally.

Volume is healthy at 6,190 a month. The category consolidated quickly, so a well defined set of platforms compete on broadly similar economics. Predictable, and predictably expensive.

What this means for a real budget

Take $6,000 a month, a common Series A number, and spend it entirely on pentest category terms at $150 a click. That buys 40 clicks. At a 2% conversion rate it is under one lead a month.

The same budget in AppSec at $30 buys 200 clicks. In zero trust at $25 it buys 240.

This is the arithmetic behind founders concluding that paid search does not work in security. What actually failed was entering the auction at its most expensive point with a budget sized for a different game.

Two things change that math. Bidding on comparison, alternative and requirement terms rather than category heads, which costs a fraction and sits closer to a decision. And keeping the 40% to 60% of budget that reaches non-buyers out of the account in the first place, which in this category means a governed negative keyword list built for security’s unusually heavy career and student search traffic.

At $150 a click, one wasted click costs more than an entire lead does in most other categories.

What I am not claiming

I would rather state the limits than have you find them.

These are calibrated estimates, not measured cybersecurity CPC. The calibration is real and measured across 249 keywords. Applying it to cybersecurity is an inference.

The calibration came from accounts outside cybersecurity. The 5 accounts measured are legal, tax and healthcare-information software. Auction dynamics differ by category, and this is the weakest link in the chain.

36 seed terms across 15 categories is a sample. Ranges are the minimum and maximum of the high estimate within each category, not a full distribution.

US, English, Google Search only. Microsoft Ads runs materially cheaper in most B2B categories and none of this describes it.

What I am confident about: $35.80 does not describe this market, Google’s high estimate runs about 2x above non-brand reality, and the spread between the most and least expensive category in security is close to 10x.

Common questions

Why not just use Keyword Planner myself?

You can and you should. The gap this fills is the calibration. Keyword Planner alone gives a bid estimate running roughly double what non-brand keywords actually cost, and nothing in the tool tells you that. Pull your own numbers, then multiply the high estimate by about 0.56 for non-brand terms.

Does this apply to Microsoft Ads?

No. Microsoft Ads typically produces materially cheaper clicks in B2B categories, and often better cost per qualified opportunity, because the auction is thinner. That deserves its own measurement rather than an assumption.

My CPC is far below these numbers. Is something wrong?

Probably not, and it is worth checking why. The most common reason is that a large share of your spend is brand traffic, which prices at roughly a fifth of category terms. Split brand from non-brand and look at the non-brand figure alone before concluding your account is efficient.

These prices are impossible for our budget. What now?

That is a fair conclusion about category head terms specifically, and it does not mean the channel is closed. Comparison and alternative terms in the same categories price far below these figures and convert closer to a decision. Start there rather than at the head.

None of this tells you whether your own clicks are priced well, because that depends on which queries you are actually buying.
