A cybersecurity-focused exchange-traded fund (ETF) lets you invest in a basket of companies in the sector instead of choosing one cybersecurity stock. U.S.-listed examples include BUG, CIBR, HACK, and IHAK. They follow different indexes and have different holdings and costs, so compare their current prospectuses, portfolios, and trading conditions before investing. A sector ETF spreads company-specific exposure across multiple holdings, but it is still a concentrated equity investment and can lose value.
How a cybersecurity ETF works
An ETF holds a portfolio of securities and trades on an exchange. A cybersecurity ETF selects companies according to its index or investment mandate. That gives you exposure to multiple businesses without making your outcome depend on just one company.
The trade-off is that the fund remains focused on a single industry. Its holdings may move together when technology or growth stocks fall, and cybersecurity companies can face competitive and business risks. ETF shares also trade at market prices that may differ from net asset value (NAV), so the price you pay or receive can be affected by the bid/ask spread.

These are examples, not a ranking. Figures below are reported by the issuers or in their SEC-filed summary prospectuses; they have different dates and may change.
#1 Best Overall
| ETF | Index or investment focus | Reported expense | Other reported details |
|---|---|---|---|
| BUG — Global X Cybersecurity ETF | Indxx Cybersecurity Index | 0.50% total annual operating expenses in the summary prospectus filed April 1, 2026 | Normally invests at least 80% of assets in index securities and related depositary receipts; most recent fiscal-period turnover was 35.93%. SEC-filed summary prospectus |
| CIBR — First Trust Nasdaq Cybersecurity ETF | Nasdaq CTA Cybersecurity Index | 0.58% total annual operating expenses after fee breakpoints in the summary prospectus filed February 2, 2026; the contractual fee absent breakpoints is 0.60% | Most recent fiscal-year portfolio turnover was 21%. SEC-filed summary prospectus |
| HACK — Amplify Cybersecurity ETF | ISE Cyber Security Select Index; companies involved in cybersecurity solutions across hardware, software, and services | 0.60% total expense ratio, as of October 2, 2026 | 23 holdings as of October 2, 2026. Amplify fund page |
| IHAK — iShares Cybersecurity and Tech ETF | Global companies involved in cybersecurity hardware, software, and services across developed and emerging markets; tracks the NYSE FactSet Global Cyber Security Index | 0.47% expense ratio, as listed October 1–2, 2026 | 34 holdings and a 0.16% 30-day median bid/ask spread, both reported as of October 2, 2026. iShares fund page |
An expense ratio is an ongoing fund expense, not the full cost of buying and holding shares. Brokerage charges, trading spreads, taxes, and differences between fund and index performance can also affect your result. Compare the current prospectus and fund page because fees, holdings, and other details can change.
How to compare funds before investing
-
Check the index rules
BUG, CIBR, HACK, and IHAK track different indexes. Their eligibility rules, weighting methods, and rebalancing can produce different portfolios even when the funds share a cybersecurity theme.
-
Inspect holdings and concentration
Review the latest complete holdings and the weight of each large position. A fund with more holdings is not automatically less concentrated: a few large positions may still account for much of its assets. Also consider whether a company earns a substantial share of its revenue outside cybersecurity.

Compare total investing costs
Look beyond the expense ratio. Check your broker’s trading charges, the bid/ask spread, and whether shares are trading at a premium or discount to NAV. Your tax treatment depends on your circumstances and jurisdiction.
-
Understand geographic exposure
Check whether the fund is U.S.-focused or global, and examine where its holdings are based. A global mandate does not guarantee balanced exposure across countries or regions.
-
Decide what role it should play
Consider whether a sector fund belongs as a limited allocation alongside a broadly diversified portfolio, rather than treating it as a replacement for one. The right allocation depends on your goals, time horizon, existing investments, risk tolerance, and financial circumstances.
What a cybersecurity ETF does not protect you from
- Sector declines: Multiple holdings can fall together when technology shares or growth stocks are under pressure.
- Loss of principal: The share price can decline, and you can lose money.
- Trading-price differences: ETF shares trade at market prices that can differ from NAV; spreads and brokerage charges affect transaction results.
- Index and fund costs: Index returns are not directly investable and generally do not include a fund’s expenses. A fund’s results can differ from its index.
- Company-specific risks: A basket reduces reliance on a single company but does not eliminate the risks of the businesses it holds.
Amplify warns that “Narrowly focused investments typically exhibit higher volatility.” Its HACK fund page also describes competitive risks for technology companies.

Past performance is historical, not a forecast, and should not be used alone to select a fund. For example, First Trust reported CIBR’s NAV total return as 40.36% year-to-date and 37.44% over one year through August 31, 2026. Those figures describe that fund’s performance through that date; they do not predict future returns. First Trust notes that actual investor returns may differ. See the First Trust CIBR fund page for performance information and its stated period.
Best Value
Before you buy
- Read the fund’s latest statutory prospectus and review its objective, risks, fees, index, and holdings.
- Check your broker’s terms and the fund’s current market price, spread, and NAV information.
- Confirm that the ETF is available to you and understand the tax and investment rules that apply in your country.
- Decide how the fund fits with the rest of your portfolio; do not assume that a sector basket is equivalent to broad-market diversification.
