A cybersecurity exchange-traded fund (ETF) lets you invest in a basket of companies in the sector rather than choosing one cybersecurity stock. Funds such as BUG, CIBR, HACK and IHAK use different indexes and holdings, so compare their construction and costs before deciding whether one fits your portfolio. A sector ETF still concentrates risk in cybersecurity and technology; it is not a substitute for broad-market diversification.
How a cybersecurity ETF gives you a basket of stocks
An ETF pools investor money to hold a portfolio of securities. Buying shares of a cybersecurity ETF gives you exposure to multiple companies selected under that fund’s index or investment rules. It reduces reliance on one company, but it does not remove the possibility of losses: the fund’s holdings can fall together, and the share price can decline.

How four cybersecurity ETFs differ
| Fund | Index or exposure | Reported costs and portfolio details |
|---|---|---|
| BUG — Global X Cybersecurity ETF | Seeks to correspond generally, before fees and expenses, to the Indxx Cybersecurity Index. The April 1, 2026 summary prospectus says it normally invests at least 80% of assets in index securities and related depositary receipts. | 0.50% total annual operating expenses; most recent fiscal-period turnover was 35.93%. Brokerage and intermediary fees may be additional. SEC-filed summary prospectus |
| CIBR — First Trust Nasdaq Cybersecurity ETF | Seeks generally to track the Nasdaq CTA Cybersecurity Index. | 0.58% total annual operating expenses after fee breakpoints; the contractual fee absent breakpoints is 0.60%. The prospectus reports 21% portfolio turnover in the most recent fiscal year. SEC-filed summary prospectus |
| HACK — Amplify Cybersecurity ETF | Benchmarked to the ISE Cyber Security Select Index; Amplify describes exposure to cybersecurity solutions across hardware, software and services. | 0.60% total expense ratio and 23 holdings, as of October 2, 2026. Amplify fund page |
| IHAK — iShares Cybersecurity and Tech ETF | Tracks a global equity index of companies involved in cybersecurity hardware, software and services across developed and emerging markets; the index is NYSE FactSet Global Cyber Security. | 0.47% expense ratio and 34 holdings as of October 1–2, 2026. The 30-day median bid/ask spread was 0.16% as of October 2, 2026. iShares fund page |
Expense ratios and holdings can change. The figures above are issuer-reported and dated as stated; use the latest fund page and prospectus for current information. A lower expense ratio alone does not establish which fund is the better fit.

What to compare before choosing a fund
Index rules and holdings
Each ETF follows a different index, and eligibility and weighting rules shape what you own. Review the full, current holdings list and the weight of the largest positions. A fund with more holdings is not automatically less concentrated: a few large positions may account for much of its assets, and some companies may have substantial businesses outside cybersecurity.
All-in investing and trading costs
The expense ratio is an ongoing fund cost, not necessarily the full cost of owning ETF shares. Also check brokerage charges, the bid/ask spread and whether shares are trading at a premium or discount to net asset value. Spreads and trading charges affect the price you pay or receive; taxes depend on your circumstances and jurisdiction.
Geographic exposure and portfolio role
Check whether the fund holds U.S. companies only or includes global exposure, and how its index weights and rebalances constituents. Consider whether a sector fund would be a limited allocation alongside diversified core holdings rather than a replacement for them. The suitable allocation depends on your goals, time horizon, existing portfolio and risk tolerance.

- Sector concentration: A cybersecurity ETF focuses on a narrow industry, not the whole economy. Holdings may move together when technology or growth stocks decline. Amplify warns that “Narrowly focused investments typically exhibit higher volatility.” Amplify HACK fund page
- Market and principal risk: ETF shares can lose value, and investors can lose principal. Owning several cybersecurity companies does not protect against a broad equity-market decline or problems affecting the sector.
- Trading-price risk: ETF shares trade on exchanges at market prices that may differ from net asset value. The spread and any premium or discount can affect your result.
- Tracking and expenses: An index’s return is not directly investable and usually does not include a fund’s expenses. A fund’s result can differ from its index.
How to read performance figures
Historical returns are tied to a specific period and calculation. First Trust reported CIBR net asset value total return of 40.36% year to date and 37.44% over one year through August 31, 2026. First Trust cautions that past performance does not guarantee future results and that actual investor returns may differ. Those figures describe that period only; they are not forecasts and should not be used alone to select a fund. First Trust CIBR fund page

Practical steps to invest
- Check your starting point. Review your existing investments, goals, time horizon and tolerance for a concentrated sector allocation.
- Compare current documents. For any fund under consideration, check its prospectus, index, full holdings, expense ratio and issuer’s latest risk disclosures.
- Check your trading terms. Confirm that the fund is available through your brokerage and review any commission, spread, tax or other account-specific considerations.
- Decide on a portfolio role. Determine whether the investment belongs, if at all, as a limited sector holding alongside diversified investments. A ticker or past return cannot determine the right allocation for you.
